2 Wind Park Control Concept Active power control TSO Cluster Controller Weather Monitor Weather Monitor Reactive power control Control of up to 2500 turbines Scalable concept LVRT handling Grid code compliance Park Controller Grid Monitor Cluster Controller Open Control of Wind Parks Today s wind turbines and wind parks grow increasingly larger as the demand for flexible controlled power in the grid increases. In order to control these wind parks, ensuring that they are balanced and able to comply with the grid codes all over the world, Mita-Teknik offers an open, reliable, flexible and intelligent Wind Park Control Concept that gives our customers the edge when selling their wind turbines for wind parks all over the world. How it Works The hierarchical Wind Park Control Concept consists of our field-proven hardware suitable for the harsh environment, and multiple software packages. All units are interconnected by an Ethernet network running the reliable M-Link protocol. The wind parks is controlled by a Park Controller that dispatches the active and reactive power set points, as ordered by a Transmission System Operator (TSO) either directly to the Wind Turbine unit, or via a Cluster Controller that can be introduced in large wind parks or when there is more than one point of common coupling to the grid. At the point of common coupling, a Grid Monitor can be installed to accurately measure the grid characteristics and send them back to the Park/Cluster Controller for further control. As part of the concept, a Weather Monitor may supply the Park Controller with meteorological data. By doing so, you can, for example, produce a wind farm power curve or take special functions like humidity, ice and ambient light detectors into account (upon request). All functions can be setup, monitored and data extracted either directly on the unit or via complete remote control. Highly Scalable Solution Whether you are installing only a few or even hundreds of turbines, there is one solution that fits your needs! Our concept supports from 1 to 2500 turbines in 0 to 50 clusters with individual grid and weather measurements and output control in each cluster. SCADA Integration Naturally, the concept is fully integrated on all levels in the SCADA system, Gateway, so that you can monitor, supervise and setup the wind, no matter if you are on site or on the other side of the world. Open Flexible System The concept is designed to be open and flexible, supporting open configurable standards for control and supervision like: OPC IEC (MMS) Modbus MT_Wind Park Control Concept_DataSheet_R4_0

3 Wind Park Control Concept Multiple TSO Interfaces Communication with the TSO, e.g. the utility company, is often different from country to country and from TSO to TSO. To make things easier, Mita-Teknik offers a variety of configurable interfaces for exchanging data with the Transmission System Operator, e.g.: Analog inputs/outputs Digital inputs/outputs Modbus OPC IEC (MMS).. Built-in Grid Code Support Often, grid codes vary from country to country, making it difficult to comply with all codes in one solution. The Wind Park Control Concept accommodates this by offering offthe-shelf grid codes support like European and Chinese etc. This makes it easy for you to enter new markets without having to think about compliance with local grid codes. Should a required grid code not be in our database, our grid experts can of course help to analyze and implement it. Reliable Park Communication The communication protocol used internally in the system is our reliable M-Link protocol. The protocol provides very stable and secure communication via cost-optimized network components. Backward Compatible If you have wind parks running on the WP3x00 platform, the new features of the Wind Park Control Concept can of course be utilized. By using the Mita-Teknik ES Ethernet switches and the M-Net communicator software, the previous generation of controllers can be brought up to speed with the newest grid codes requirements etc. Concept Solution or Tailor-made With close to 30 years of experience within the wind industry, Mita-Teknik has compiled a Wind Park Control Concept that will fit most needs concerning e.g.: Park/Cluster Controller, Grid Monitor and Weather Monitor Fully tested software for controlling the individual wind park components Accessories Installation and commissioning services Integration services Training services However, should you require solutions for special purposes we are always prepared to compile a tailor-made solution that fits your specific needs.

13 Wind Park Control Concept Software Grid Controller Application (GCA) Advanced active power control Rate Control of Active Power Production Start/Stop Manager for Wind Turbines Universal interface to wind turbines Advanced Reactive Power Control Ramping Rate limitation of individual wind turbine and complete park set points Possibility to set individual wind turbine/cluster set points Wind Park active power capability calculation Grid measurements selectable from the point of common coupling or a sum of wind turbine/cluster power values Wind Park Weather data gathering Grid Controller Application (GCA) The main function of Grid Controller Application (GCA) is handling the control of wind turbines or clusters in the wind park. One Grid Controller application is able to control up to 100 wind turbines (only for WP4200 Controller Platform) and up to 50 wind turbines for other controllers` types. It is possible to connect up to 10 cluster controllers to one wind ler. Also GCA supports up to 5 grid measurement stations and up to 3 weather stations. Installation The GCA can be installed on a WP4100, WP4200 or WP100 Controller Platform on the Wind Park and/or Cluster controller. Active Power Control The purpose of the wind park Active Power Control is to limit the total generated active power according to the Transmission System Operator (TSO) demand or locally set limit. The TSO can order the wind park to operate either with unlimited or limited active power production via the P10518 TSO Client Application. The GCA is responsible for keeping the active power limitation at the point of common coupling (PCC). Reactive Power Control The Reactive Power Control for wind parks is very important for successfully integration of wind power into the electrical grid. Grid codes require wind parks to be able to adjust their power factor or reactive power to TSO requirements to meet system operating conditions. GCA receives a set point from TSO and uses the reactive power capabilities of the wind turbines, which are equipped with inverters to regulate reactive power at the point of common coupling. Rate Control If Rate Control function is enabled, the Wind Park Controller will monitor the change rate of wind park active power output. If the change rate of power output is more than limit value, the Wind Park Controller will generate a power limiting set points to each wind turbine to keep the change rate of collective active power output below configured limits. Start/Stop Management Start/Stop algorithm is useful when it is not possible to reduce park active power by wind turbines pitch system. The algorithm examines the need of starting or stopping of wind tubrbines by comparing the value of not regulated active power to the value of active power set point. Then Grid Controller application is able to stop or start wind turbines in accordance with one of selected strategy and defined for each wind turbine priority.

18 Wind Park Control Concept Software Transmission System Operator Client Application (TSO) Configurable I/O interface to grid company Active power limitation Active power reserve (delta) control High and low frequency response Reactive power control Power factor control cos(ϕ) (P) control Voltage control Transmission System Operator Client Application (TSO Client) The TSO Client handles the communication between the grid operator and Wind Park Controller. Based on the commands from grid operator and grid security parameters, calculated inside the application, the TSO Client generates active and reactive power set points for Grid Controller or Data Bridge Applications. Installation The TSO Client application is installed on a WP4100, WP4200 or WP100 Controller Platform on Wind Park or Wind Turbine controller. On a stand-alone wind turbine, the TSO Client makes it possible to have the same interface tothe grid operator as in larger systems. Wide Range of Interfaces TSO Clients provides a wide range of possible interfaces so that active power, reactive power, power factor and voltage at the point of common coupling can be controlled from outside and necessary data can be signaled back. Active Power Reserve (Delta) Control The Active Power Reserve Control function allows the grid operator to run the wind park with a constant reserved active power based on the capability value. Reserved active power can be used to support eventual power grid contingencies by allowing the wind park to increase the active power output in case it is required. High and Low Frequency Response The TSO Client Application is able to reduce the park active power automatically if high frequency is detected according to the defined gradient. It is also possible to use low frequency response if the wind park is running with enabled active power reserve function. The system will use reserved active power to increase the active power output during low grid frequency. Voltage Control In this mode TSO Client Application uses the reactive power capability of the wind park to control the voltage in the point of common coupling. Dependently on deviation between voltage and set point values, the TSO Client Application generates an inductive or capacitive reactive power set point to keep the voltage within the specified range. Cos(ϕ) (P) Control When mentioned above mode is selected, reactive power set point is calcualted as a cos(ϕ) value which proportionally depends on the currently active power production. Grid Code Compliance The TSO Client Application is designed so a wide range of grid codes and grid operator interfaces can be accommodated. MT_Wind Park Control Concept Software_DataSheet_R4_0

22 Wind Park Control Concept Software M-Net Communicator Application (MCA) M-Net communication via redundant Ethernet rings M-Net communication via serial rings Communication with 50 WP3x00 controllers 10 simultaneous Gateway connections to the wind park network Up to 4 remote display sessions to one WP3x00 controller Integrated with wind solution M-Net Communicator Application (MCA) The MCA converts Wind Park controller to the M-Net communication router from locally or remotely installed Gateway SCADA systems to the wind park network with Ethernet or serial M-Net topology. The application also provides the communication between the Grid Controller Application and the WP3x00 Controllers. Installation The MCA is installed on a WP4100, WP4200 or WP100 Controller Platform on Wind Park or Cluster Controller together with Grid Controller Application. M-Net over Redundant Ethernet Rings The MCA can communicate with WP3x00 Controllers via redundant Ethernet rings. In that case, each WP3x00 Controller must be connected to the COM-port of Mita- Teknik ES1000 Ethernet switch. M-Net over Serial Rings Network configurations where WP3x00 Controllers are connected as one or more serial rings are also supported. Each such ring can be connected to the ES1000 COM-port or directly to the COM-port of Wind Park controller. Gateway Connections The M-Net Communicator Application manages up to 10 simultaneous Gateways SCADA system connections to the Wind Park. Different users can simultaneously monitor the same wind turbine and open up to 4 remote display sessions. Wind Park Control Thanks to MCA, wind turbines with WP3x00 Controllers are fully integrated to the new Mita-Teknik Wind Park Control Concept. Application prioritizes the data related to Park Control. This ensures control of the wind park in realtime, even if communication is overloaded. Multiple Fast Communications By using Ethernet and multiplexing technology, the MCA also makes it possible to access the individual controllers much faster than the original network and with up to 10 Gateway connections per unit/turbine. This is a big step up for existing parks that need multiple users to connect or stream real-time data via OPC, Modbus or other standard protocols.
