摘　　要：针对发电机网源协调特性获取不准确,机组不能按要求出力等问题,本文提出了一种新型网源协调在线监测系统。该系统实时采集发电机的励磁、调速系统运行控制信息,并上送至调度主站。该系统能够及时捕捉系统扰动,对励磁、调速系统涉网性能进行评价,并具有预警功能。此外,该系统能够对发电机组控制系统参数进行巡检和管理。实际应用表明,该系统加强了电网与电厂对机组状态的监测,对电网安全稳定运行具有积极意义。Aiming at the problems of inaccurate acquisition of generator network source coordination characteristics and inability of generating units to produce power as required,a new on-line monitoring system for network source coordination is proposed in this paper.The system collects real-time excitation and speed control information of generators and sends it to dispatching master station.The system can catch system disturbance in time,evaluate the performance of excitation and speed control system,and has the function of early warning.In addition,the system can inspect and manage the parameters of generator control system.Practical application shows that the system strengthens the monitoring of power grid and power plant for unit status,and has positive significance for safe and stable operation of power grid.
