3 Application information 1. Application information 1.1 eneral information Application The Automatic enset, AC, is a control unit containing all necessary functions for protection and control of a genset. It can be used as a single unit for one genset, or a number of ACs can be connected in a complete power management system for synchronising projects, islanded or paralleled to the mains. The AC contains all necessary 3-phase measuring circuits, and all values and alarms are presented on the sunshine proof LCD display. The AC is a compact all-in-one unit designed for the following applications: Standard plant modes Island mode Automatic Failure Fied power Peak shaving Load takeover power eport Remote maintenance Applications Power plant with synchronising generators or a stand-alone generator. Can also be used in critical power plants. Critical power/emergency standby plants, black start generator. Power plant with fied kw setpoint (including building load). Power plant where generator supplies peak load demand paralleled to the mains. Plant mode where the load is moved from mains to generator, e.g. peak demand periods or periods with risk of power outages. Power plant with fied kw setpoint (ecluding building load). Used when the generator has to supply the load while a distribution transformer needs to be disconnected for service. The plant modes are configurable, and it is possible to change the plant mode on the fly both in single and in power management applications. All modes can be combined with Automatic Failure mode (AMF). Remote maintenance requires a DEIF RMB bo (separate product) and a set of cables (option J8). The plant/genset is easily controlled from the display unit, or a HMI/scada system can be implemented using one of the communication options. Three display units can be installed per control unit Application emulation In order to verify and test the functionality of the application, it is possible to use the emulation tool of the AC. Being connected to the AC gives the possibility to test a majority of the functionality, e.g. plant modes and logics, handling, mains and generator operation. Application emulation is useful for training, customising plant requirements and testing basic functionality that needs to be set up or verified. DEIF A/S Page 3 of 30

11 Application information 1.2 Power management applications The purpose of the power management system is to implement one control system that controls all s and all gensets. This can for instance be for fuel optimised purposes, for easy implementation of plant logic or for safety reasons Application The plant modes supported by the power management options are: Standard plant modes Island mode Automatic Failure Fied power Peak shaving Load takeover power eport Applications Power plant with synchronising generators or a stand-alone generator. Can also be used in critical power plants with a start signal from an eternal (ATS) controller Critical power/emergency standby plants, black start generator Power plant with fied kw setpoint (including building load) Power plant where generator supplies peak demand Plant mode where the load is moved from mains to generator, e.g. peak demand periods or periods with risk of power outages Power plant with fied kw setpoint (ecluding building load) The plant modes are configurable, and it is possible to change the plant mode on the fly both in single and in power management applications. The plant can be divided by one to eight bus tie s making it possible to run the plant with different plant modes, e.g. for test purposes or when splitting up the load in primary and secondary loads Description The AC can be equipped with a power management option (4, 5, 7 or 8). Using this possibility, the AC will be able to handle simple or advanced applications for a great number of power plant projects within synchronising gensets, critical power/emergency standby applications or power producing applications. The following number of units can be controlled: 16 mains feeders with mains and tie 8 bus tie s on the generator bus or load bus 16 generators (256 in plant management applications) with generator s The complete power management system can easily be monitored from the PC utility SW through a graphical supervision page. Running status, hours in operation, status, condition of mains and busbars and fuel consumption are just some of the values that are presented. DEIF A/S Page 11 of 30

13 Application information Easy configuration of single line diagrams The setup of the application is easily configured using a PC and the DEIF PC utility software. Your PC tool visualises it - the AC-4 realises it. The basic plant control is set up by a few basic plant conditions including mains feeder handling and operation of the generators Safe power management system Multi-master system Redundant CANbus Redundant controller The AC power management system is designed as a multi-master system for increased reliability. In a multi-master system all vital data is transmitted between the ACs, giving all units knowledge of the present power management status (calculations and position) in the application. This philosophy makes the application immune to failing master controllers and makes the AC suitable for all types of applications, i.e. emergency standby/critical power applications. In critical power/emergency standby applications requiring etra operation reliability, redundant CANbus communication lines can be used to ensure reliable CANbus communication for power management if one of the CAN lines are damaged. With the Critical Power option (T1) it is possible to have redundant controllers in the application. The redundant controller is connected on the CAN line as a hot standby unit and is therefore always updated with the system status and ready to become the primary controller. DEIF A/S Page 13 of 30
