山东电网500kV系统黑启动试验方案研究

Black Start Test Scheme for Shandong 500 kV Power Grid

研究山东电网500 kV系统黑启动试验,确定黑启动电源和方案。分析黑启动过程中的发电机自励磁、工频过电压、频率和电压稳定、厂用负荷恢复以及小系统的稳定性等问题,首次提出利用零起升压方式进行通道恢复的概念和方法,并进一步分析黑启动过程中应注意的问题。山东电网500 kV系统黑启动试验的成功证明所选方案及分析计算的有效性和合理性。

The black start test scheme for Shandong 500 kV power grid was presented in this paper.The problems such as selfexcitation of generator,power frequency overvoltage,stability of voltage and frequency,restoration of auxiliary power,and stability of small power system during the black start were analyzed.The path restoration with the mode of raising voltage from zero was put forward for the first time,and the problems which should be paid attention to during black start were discussed.The validity and rationality of the selected scheme and calculation were demonstrated by the black start test of Shandong power grid.
