单台机组带厂用电运行方式的可行性分析

Analysis of feasibility of single power unit independent operation mode providing auxiliary power of whole plant

介绍了托电公司主接线概况,在此基础上分析了机组全部停运导致500 kV母线失电的风险因素,从发电机频率、电压的控制及运行调整的角度出发,讨论了在托电公司4条出线全跳情况下保留#4机组带厂用电的可能性。

The main connection of the Togtoh Power Generation Company Limited was introduced. Based on this,the risk factors of voltage outage on 500 kV line caused by shutdown of all power units were analyzed. Starting from the viewpoints of frequency and voltage control and operation adjustment of the generator, the feasibility to provide the company-wide auxiliary power system by one unit No. 4 under condition of all the four output line trip-out was discussed.
