1 Protection and control Sepam 2000 Sepam Sepam 100

2 Sepam concept Mastery of digital techniques Electromagnetic compatibility testing is performed in an anechoic chamber. As a result of the success of the first Sepam unit, Merlin Gerin developed a new range: Sepam and Sepam 2000.This range is more comprehensive, more effective and fully appropriate for the control of electrical substations in public and industrial distribution systems. All protection and control devices must: c supply optimal service under the best security and availability conditions, c ensure dependable operation in the highly disturbed electrical substation environment. To achieve these objectives, the development of this new range called for substantial implementation of expertise and enhanced investigations in the following main areas: c electrical phenomena, transient operation, c signal processing, c protection algorithms, c electromagnetic compatibility (EMC), c dependability, reliability, c communication networks. During the design phase, dependability studies (FMECA ) were carried out to determine the hardware and software architectures, considerably improving availability and operating security. All the studies were performed in accordance with a stringent quality plan. A large number of qualification tests were performed, in a dedicated protection testing laboratory (Kirchhoff laboratory). The protection functions are tested in the laboratory by simulating the phenomena (EMTP (2) ) as they appear in electrical networks. Major advantages The use of digital techniques provides protection and control devices with major advantages: Kirchhoff protection testing laboratory. Availability The use of extensive self-testing and self-diagnosis procedures allows wide-range monitoring of the device. The user is continuously informed of Sepam s operating condition. He can therefore take immediate and efficient action in the event of a failure. The risk of running an installation with faulty protection is substantially lowered. Periodic testing is no longer essential. Global cost reduction The integration in a Sepam of all the functions needed for the protection and control of a system offers substantial advantages such as more rational operation, optimized performance and better service for a reduced overall cost. Reduction in the cost of: c design: by the choice of units that are ready to use, without requiring detailed engineering work, c installation: by the integration of auxiliary relays, measuring instruments and annunciation devices, c commissioning: by simple installation and testing, c operation: by remote control and improved access to more complete information, c maintenance: by the reduction of preventive maintenance. Dependability Extensive dependability and reliability calculations have been carried out on Sepam. They show that the failure rate, and therefore the risk of misoperation, is minimized with an integrated Sepam type solution. Simplicity Sepam requires only simple parameter setting (calibration of the current and voltage transformers, and general information on the network). FMECA: Failure Modes, Effects and Criticality Analysis. (2) EMTP: Electromagnetic Transient Program. Flexibility The flexibility of Sepam 2000 s built-in PLC makes it suitable for all possible control logic schemes. 2

3 A complete range All applications The is a set of protection and control units which have the capacity to fullfil all types of applications: c substations, c busbars, c transformers, c motors, c capacitors, c generators, c measure and control. Each Sepam is an optimized solution in terms of functions, performance and price. A complete range: Sepam 100, Sepam and Sepam All functions Each Sepam includes all the protection, metering, control, monitoring and annunciation functions required for its assigned application. The functions have very wide setting ranges, all types of curves, and can therefore fit into any protection system. The choice of functions offered in each Sepam is the result of the engineering, experience and expertise of Merlin Gerin specialists who are confronted daily with the challenge of developing electrical equipment projects. In addition, the so-called logic discrimination function makes it possible to further lower the tripping time when a fault occurs, whatever the time discrimination intervals and the type of curve (definite time or IDMT). This principle makes it possible to incorporate economical busbar protection, or to set a shorter protection time delay upstream than downstream, and still maintain tripping discrimination. It means that Sepam can meet the protection and control needs of low voltage networks and high voltage networks up to 220 kv as efficiently as required. Industrial range The design of all the types of Sepam for each application is based on two hardware units: Sepam series and Sepam 2000 series. The hardware manufacturing process is ISO9001 certified and includes a burn-in cycle. Sepam s robustness and its outstanding electromagnetic compatibility (EMC) allow it to be used in highly disturbed environments without requiring any particular precautions.

4 Sepam 2000 Presentation Standard (S36) Sepam 2000 and compact (S26) Sepam Standard Sepam 2000 is delivered with its connectors. Sepam 2000 is focused on performance. It can be used for the most demanding applications. Sepam 2000 has a large control and monitoring capacity, provided by its built-in PLC and interface for communication with a centralized control system. The built-in PLC considerably cuts down on the use of auxiliary relays and the associated wiring. Each Sepam 2000 is supplied with its standard control and annunciation program, which allows it to be used without any additional engineering work or programming. The available data as well as Sepam 2000 s remote control capacity enable it to be integrated in an energy management system. Sepam 2000 reports to the control room, so the user is immediately informed of any situation. Having this information at his disposal, he can take the appropriate measures without leaving the control room. Each Sepam 2000 is designed to meet all the application needs and includes all the necessary functions, ready for use. Simply choose the appropriate Sepam 2000 from the selection tables showing the functions available for each application : c substations, c busbars, c transformers, c motors, c capacitors, c generators. Example : An incomer in a substation with multiple supply sources, in a high impedance earthed system, should be equipped with: c definite time or IDMT phase overcurrent and earth fault protection, c directional overcurrent and, sometimes, directional earth fault protection for discrimination between parallel incomers. c an undervoltage relay to control supply source changeover. c all the measurements and accumulated energy readings needed to operate the substation. For this application, the S03 type Sepam 2000 could be chosen, including the standard control and monitoring functions, such as trip circuit supervision and logic discrimination. for public distribution application, please consult us. 4

5 Control logic and annunciation Each type of Sepam 2000 is equiped with a built-in PLC with at least 10 logic inputs and 6 logic outputs (which can be extended to 26 inputs and 14 outputs). This flexibility is provided for standard network management automation functions such as logic discrimination, reclosing, load shedding, etc. Customized process control programs may also be developed on Sepam (see for customized applications document). Simple setting with the TSM 2001 pocket terminal. Description Sepam 2000 replaces measuring instruments such as ammeters, voltmeters, wattmeters, energy meters, etc. It displays alarm and operating messages related to the protection functions and control logic systems, thereby eliminating the many indicating lamps found on previous installations. The front face includes: c a lighted alphanumerical display, legible from a distance of several meters, c keys to select the measurement to be displayed and to acknowledge messages. As a security feature, these keys do not give access to the protection settings, c 3 lights: v trip (tripping by the protective relay), v circuit breaker open, v circuit breaker closed, c a green light indicating the presence of auxiliary power supply, c a red light signalling malfunctions and relay fail-safe position (watchdog), c a door for access to: v to the serial connection inlet, v the cartridge slot. The cartridge contains the different programs required for Sepam 2000 operation. Operation Sepam 2000 is simple to consult and set thanks to the serial link on the front of the device. The settings may be made on the front panel (serial link): - one by one, using the TSM2001 pocket terminal, or the SFT2801 PC software program, - all at once using the SFT2821 PC software program (downloading), The TSM 2001 pocket terminal is equiped with a keyboard, a 4-line display (20-character per line) and a menu system. It is easy to read measurements, enter settings, modify operating conditions and review maintenance information such as fault current, number of c.b. operations, etc. Access to the protection function settings is protected by a password. Sepam 2000 stores the parameters and the settings in its non volatile memory. In the event of an auxiliary power supply failure, they are saved and retrieved as soon as the power is restored. Disturbance recording Sepam 2000 has a high performing disturbance recording function. It is used to record analog signals (current/voltage) and logic states during a time interval which includes the disturbance. Sepam 2000 also has a graphical wave form recovery software package for the analysis and use of the data (SFT 2826). Communication Sepam 2000 offers the option of a high performing communication module. (Jbus/Modbus or other) * for connection to a remote control and monitoring device. This option provides: c measurement of electrical variables c annunciation, c switchgear control c reading and modification of settings c network diagnosis by : v event logging v graphical wave form display. Installation and connection Sepam 2000 is delivered with its connectors. The connectors are individually disconnectable screw-on terminals. All types of Sepam can be installed by making a simple rectangular cut-out in the mounting support. Some types of Sepam 2000 also come in a compact version (S26). (*) please consult us. 5
