Automation system Integrated for monitoring and protection

The integrated automation system is an integrated automation device that integrates intelligent software and functions such as microcomputer protection, monitoring, simultaneous grid connection, temperature measurement, speed measurement, water level acquisition, generator excitation, turbine speed control, and public and auxiliary equipment control.

the automation system integrated auxiliary equipment such as, generator excitation system,inlet valve, speed governor,  circuit breakers, switches and other primary equipment. it can meet the needs of hydropower station users  with one-button start/stop, fast automatic grid connection,  realizing the function of hydropower station “no-person onduty”.

Main function

• Relay protection
  The system has directional current quick-break protection, directional time-limited current quick-break protection, over-current protection, overload protection, negative-sequence over-current protection, zero-sequence over-voltage protection, over-voltage protection, low-voltage protection, frequency protection, loss of magnetic protection, non-electricity Protection and other functions.
• Monitoring function
  The system mainly monitors three-phase current, three-phase phase voltage, zero-sequence voltage, active power, reactive power, power factor, generator frequency, system frequency, etc., DC analog measurement (0~5V or 4~20mA), residual voltage Frequency measurement, temperature measurement and digital monitoring.
• unit control function
  The system has automatic control according to water level, automatic adjustment according to given power, automatic start and stop control of the unit, automatic quasi-synchronous closing, remote control of circuit breaker, unit accident shutdown, emergency stop control, etc., and reactive and reactive Adjustment function.
• Communication function
  Support multiple RS485 and Ethernet communication, support MODBUS standard protocol and custom protocol.
