浅谈厂站综合自动化（Discussion on comprehensive automation of plant and station） Discussion on comprehensive automation of plant and station Li Gaofeng Qinghai Golmud Haixi power company In recent years, along with the western development, the electric power industry is the extraordinary pace of development, step into the ranks of the automation, the area of Golmud in recent years the station automation construction, comprehensive automation of the stations new technology, new equipment and development are discussed. 1. routine station with RTU. In 1997, we began to carry out the station automation construction, and installed the first RTU (automatic centralized control console) at the 35 thousand volt Saline Lake substation. Is a conventional station, equipped with RTU and other equipment transformed from the automatic station. The switch status of substation and various power, non electricity and real-time data are monitored automatically. The disadvantage is that only part of the automation function of the four roll can be realized, and the running condition is bad, the stability is poor and the maintenance is complicated. 2. conventional relay protection combined with RTU. The old station is increased into conventional station integrated automation RTU station equipment modification, the purpose is to improve the level of automation, reduce the personnel on duty, reduce maintenance times, improve the processing speed of the accident, reduce the outage time. The goal of the transformation is not only to achieve shaking, telemetry, but also to achieve remote control, shake, adjust the four wave function. Shake signal not only to transmit digital signals, transmitting relay protection signal for dispatching automation is also, need all the content transfer station attendant inspection records and manual operation for scheduling, the dispatcher in the distance to station monitor and control, this is the comprehensive automation popular form at present. 3. microcomputer protec
