洪沟变电站SVS系统稳态控制策略的RTDS仿真试验

在分析500 kV枢纽变电站母线电压波动与交换功率波动及由此产生的无功补偿需求间的关系后,结合电网逆调压的要求,形成SVS稳态控制策略。根据取自电力调度自动化历史数据库中的500 kV母线电压历史数据,利用实时数字仿真系统RTDS对中国第一套用于输电通道枢纽变电站的大容量国产SVS系统的稳态控制策略进行长达40余小时的连续仿真。仿真试验结果验证了SVS控制策略可用性,检验了SVS控制器运行性能,优化了控制参数。

The relationship between voltage and inter-power of 500kV hub substation is analyzed and the steady strategy of SVS is presented.Real-time digital simulators(RTDS) are used to test the strategy of SVS in Honggou substation which is the first one produced in China of extra-high voltage for hub substation.The simulation data is the historical data from dispatch automation data system.The simulation during more than 40 hours optimizes the control parameters,and the simulation results show that the strategy is ...
