SID-2CM is an advanced microcomputer synchronous controller developed by a professional power equipment manufacturer, designed for relay protection and safety automatic devices in power systems. The device integrates modern electronic technology, computer technology and communication technology, and provides a high-precision and high-reliability solution for the grid-connected control of generators or lines in power stations, substations and other places. The SID-2CM synchronous device has a multi-channel grid-connected multiplexing function, which can handle grid-connected requests of multiple generators or lines at the same time, improving the operating efficiency and reliability of the power system. In addition, SID-2CM also has a precise parameter setting function. Users can flexibly adjust the closing time, allowable voltage difference, overvoltage protection value and other parameters of the circuit breaker according to actual needs to meet different grid-connected needs. |
Technical Specification: Input voltage: The voltage on the system side and the side to be connected can adapt to the AC10~264V range, and the power consumption is not more than 0.5VA at 100VAC. Recording output: When the voltage on the system side and the side to be connected is 100V, the maximum value of the recording output pulse voltage can reach 20V. Control signal relay: The capacity of the control signal relays such as "closing", "acceleration", "deceleration", "boost", "voltage reduction", and "synchronous locking" is 6A, and the contact action time is less than 2ms. Measurement accuracy: less than ±0.01Hz Working power supply: 110~220V AC and DC power supply are both available, and the power consumption is not more than 20VA. Working temperature: 0~50ºC Storage temperature: -20~70ºC Relative humidity: not more than 90% |
Product Features: - Automatically identify the nature of grid connection - Quickly capture the opportunity of grid connection - Accurate mathematical model - Fuzzy control algorithm - High reliability - Strong adaptability - Rich functions |
Application: Generator grid connection: Applicable to 1~12 generators for grid connection reuse, it can automatically identify the grid connection nature of the generator and the system, and ensure fast and smooth grid connection operation. Line grid connection: Also applicable to the grid connection operation of 1~12 lines, whether it is differential frequency grid connection or same frequency grid connection (loop closing), it can provide accurate control. Power system loop closing: When the tie line is connected between two systems that have not been decoupled, the SID-2CM synchronization device can ensure that the grid connection operation is implemented when the voltage difference and power angle on both sides of the parallel point are within a given range, avoiding the relay protection action or system loss of step caused by the redistribution of the system flow. |
