1 ////// SUBSTATIONS SEPCOS Control and protection relay

2 GENERAL INFORMATION SEPCOS represents a high-tech equipment which satisfies the most demanding safety requirements applicable to DC traction distribution networks. It is made of a powerful electronic system based on advanced technology (with several microprocessors). Used as a control and protection unit, SEPCOS integrates the necessary functions for the protection, the control and the measurement of DC traction equipment related to transportation systems (streetcars, underground railways, commuter trains or trolley buses). SEPCOS is stand alone, modular, extending and easily adaptable by software. It is equipped with a programmable logic unit which allows to freely define the operating logic functions, in order to match the requirements of the unit or the system to supervise. Moreover, SEPCOS is widely open to modern communication equipment. It delivers network communication or serial line monitoring facilities. Sécheron is the pioneer in the field of IEC adapted for DC traction power and has already successfully commissioned many projects worldwide using this standard.

3 MAIN FEATURES SEPCOS is made of several modules - power supply (PWR), processor (CPU), protection (PRO), digital inputs/outputs (DIO) - that can be adapted in order to meet the needs of each customer. Power module (PWR): VDC (50 W) VDC (35/50 W) Control and Processing Unit module (CPU): Microprocessor VORTEX86MX Protection module (PRO): - 4 digital inputs / 3 digital outputs - 4 analog inputs / 1 analog output Digital Inputs/Outputs module (DIO): - 16 digital inputs / 8 digital outputs Optical fiber connectors (the connectors present in this area depend on the type of CPU module) LVDS output for Display Watchdog Micro-SD card slot Ethernet connectors: - ETH0: PC/Switch - ETH1: Spare USB ports (A&B): Update and collect of data Oled display modules: Indication of status and diagnostic APPLICATIONS With many control/command and protection functions, SEPCOS satisfies the needs of DC power traction networks such as outgoing feeder cubicle or rectifier breaker. SEPCOS is used for monitoring traction network segments and for logging events. It analyses the current gradient and voltages through cyclic measurements at the feeding point of the substation to the catenary. The measurements are made through an electrically isolated transducer (i.e. Sécheron s VM10/ VM12 or MIU10 measuring amplifiers).

4 ARCHITECTURE All connections (power supply, analog and digital signals, network, etc.) are placed on the front panel. The power unit is modular and is chosen according to the input voltage. Different options are available for the CPU module in order to meet the customer specific needs regarding network, protocols and even redundancy. SEPCOS can include up to 5 DIO modules.

5 PROTECTIONS MAIN FEATURES For each detection, 1 set of 3 curves memorized: current (I), voltage (U), di/dt. Curve memorized pitch: 200 μs to 5 s. Sampling Rate: ~ 20 μs per analog input (total = 80 μs). Time stamps: 1 ms. Availability of the last 5000 events and 1000 curves.

I Min E T Max L+ T detection t OPTIONAL FUNCTION: CABLE INSULATION FAULT In DC traction applications, power cables built with metal shields must be protected against high touch voltage. This protection must be active when a dangerous contact voltage or a high current appear on the shield in case of insulation fault. The system is designed to detect a leak current either between shield and conductor or between shield and earth. If a fault occurs, actuation of intertripping out signal can be selected. The settings for this function can be adjusted with the S-Web tool. SEPCOS / Control and protection relay 5

6 BUS CONNECTIONS Modularity and adaptability are the key strengths of SEPCOS. Sécheron developed this control and protection relay with the objective of getting the closest match to their clients needs. Sécheron can provide engineering support while elaborating a network regardless the type of communication and its architecture. SEPCOS is indeed open to all customers networks and protocols. /// A WIDE CHOICE OF COMMUNICATION BUS Modbus-TCP Modbus-RTU Profibus-DP Profinet /// ETHERNET PROTOCOLS IEC (-5-101) IEC 61850, including GOOSE IEC PRP/HSR DNP 3.0 (Serial/Ethernet) /// FLEXIBLE CONNECTIVITY Copper cable (RS485, RJ45) Optical fiber /// REDUNDANCY Dual independent networks Parallel Redundancy Protocol (PRP) / High Availability Seamless (HSR) Bonding/Teaming network SEPCOS with optical fiber BONDING/TEAMING REDUNDANCY STAR NETWORK The bonding feature provides an interesting solution of redundancy network without huge infrastructure. Only one network interface is active while the other is simply waiting for a failure in the link (interface down or unplugged) to the primary network interface card: it will keep the network traffic up and alive.
