忻州500kV变电站投运对山西中北部电网的影响

Influence of Operation of Xinzhou 500 kV Substation on North and Central Part of Shanxi Power Grid

针对山西电网忻州500 kV变电站投产后的具体情况,重点研究了忻州500 kV变电站投产后山西中北部各种500 kV及200 kV电磁环网的运行方式,通过潮流计算、稳定校核等手段,预测了山西中北部500 kV及220 kV电网采取不同运行方式对山西电网的影响,指出了各种运行方式的优缺点,并结合山西电网的具体情况提出了有针对性的稳定控制措施。

According to the concrete condition of Shanxi power grid at the initial construction stage of 500 kV Xinzhou substation,the parallel operation of 500 kV and 220 kV power networks in north and central part of Shanxi power grid after operation of Xinzhou substation is emphatically researched. By means of the analysis of power flow calculation ,stability verification etc ,the impact of different parallel operation modes of 500 kV and 220 kV power networks in north and central part of Shanxi power grid on whole power gird is predicted. The merits and demerits of these operation modes are pointed out, considering the concrete situation of Shanxi power grid,the way of stability control to be adopted is proposed.
