概述
CSC-825 Digital Quasi Synchronization Device can merge the generator grid and close the line synchronously. CSC-825A supports 8 synchronization points. CSC-825B supports 1 synchronization point. The device can automatically recognize the parallel grid property of the parallel point breaker. It can capture the grid connection opportunity with the precise mathematical model in case of differential frequency grid connection. When the phase angle is close to zero, the device can merge the network without impact.
适用范围
CSC-825 series digital quasi-synchronous device and line selector are mainly used for the synchronous grid-connection operation of generators and the synchronous closing operation of lines, and suitable for power plants, substations and other occasions requiring synchronous grid-connection operation.
特点
①Power module and AC module are configured to be redundant. Two collection systems are independent and reliable.
②Automatically identify the grid connection of the parallel point breaker.
③Capture the first zero phase angle difference with the precise mathematical model in case of frequency difference grid connection and realize quick grid connection without impact.
④Record closing time of the breaker, provide basic data to user and send alert when the phase difference between the actual measurement value and setting is higher.
⑤Connect T second phase, phase to phase voltage and set the rotary angle via the software.
⑥Prevent against the reverse power grid connection and no power phase change on demand.
⑦Provide overvoltage protection of the generator system.
⑧Receive the input block, output block and coordinate with other devices.
⑨Provide powerful wave recording function and store 40 grid merging records.
⑩Provide diversified communication interface (RS485 and electrical and optical Ethernet network) and support multiple protocols and dual network communication.
