摘要
热工微机保护系统是具有毫秒级事故追忆功能的PLC保护系统。GPS授时装置能全天候、实时地接收GPS卫星发出的信号,获取精确的导航定位信息和精确的时间信息。通过与GPS授时装置通讯,读取GPS卫星标准时间,定期校正PLC控制器,使PLC时钟与标准时间始终保持同步,从而进一步完善提高毫秒级事故追忆功能。
Microprocessor-operated Thermotechnical Protective System is the PLC protection with SOE(1ms)funcfion.The GPS Time Receiving can receive the signal sent out by GPS artificial satellite and obtain accurate navigation allocation information and time information with all-weather real time.It can be further improve S0E function through telecommunicating with GPS time receiving,reading the GPS satellite standard time and periodically correct PLC controller to make PLC clock and standard time keep synchronously.
