基于WAMS系统的甘肃陇南电网大负荷扰动试验

Large load disturbance test based on WAMS in Long Nan of Gansu power grid

甘肃电网基于WAMS系统在220kV早成可控串补线路进行了大负荷扰动试验。通过试验实测数据和系统稳定计算结果对比分析,验证了系统稳定计算分析的正确性,校验了可控串补、PSS参数设置的合理性,考验了成碧串补站带负荷能力。同时对甘肃陇南地区进行了小干扰稳定分析,为早成线带380MW功率运行积累了第一手资料,保证了将碧口地区更多水电送入甘肃主网,同时为今后科学、合理地进行电网稳定计算、运行方式安排、借助多种手段提高电网输送能力提供了理论参考依据。

Large load disturbance of WAMS-based systems in 220 kV Zaocheng line is made.By comparing the stability calculation result and test data,the correctness of the calculation and analysis is verified,rationality of controlled series compensation and PSS parameter setting is checked,a nd the Cheng Bi series compensation stations with a load capacity is tested.And small disturbance stability test is made to accumulate first-hand information of 220 kV Zao Cheng line with 380 MW power operation.It will ensure more water power of the Bi Kou area be transmitted into Gansu main network,at the same time,provide a theoretical reference for the science and rational calculation of power system stability,operation mode arrangement,using various means to improve the power transmission capacity in future.
