摘要
针对山西电网500kV网架形成初期的具体情况,重点研究了2005年山西中南部500kV及220kV电网的电磁环网运行方式,通过分析电网的电力平衡关系、潮流计算、稳定校核,预测了山西中南部500kV及220kV电网采取不同电磁环网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电磁环网宜采用的运行方式以及采用该运行方式后需加强的工作。
According to the concrete condition of Shanxi power grid at the initial construction stage of 500kV power network, the parallel operation of 500kV and 220kV power networks in south and central part of Shanxi power grid in the year of 2005 is emphatically researched. By means of the analysis of power equilibrium, power flow calculation and stability verification, the impact of different parallel operation modes of 500kV and 220kV power networks in south 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 parallel operation mode to be adopted is proposed and the measures to be enhanced after the proposed operation mode is adopted are put forward.
