大连红沿河开机方式对黑龙江东部外送断面稳定性影响分析

Influence analysis of Dalian Hongyanhe's start-up mode on the stability of the external transmission section in eastern Heilongjiang

为了分析大连红沿河核电站接入系统后对黑龙江电网造成的实际影响,采用电力系统仿真软件PSASP,在红沿河核电站3种不同开机方式下,对黑龙江东部外送断面设置故障点,输出附近电厂的功角特性曲线。通过对实际电网进行仿真计算,验证红沿河核电站接入大电网后对黑龙江东部外送断面功角稳定性的具体影响。

In order to analyze the actual impact on Heilongjiang power grid after Dalian Hongyanhe Nuclear Power Plant is connected to the system,the power system simulation software PSASP is used to set fault points on the transmission section in the east of Heilongjiang under three different startup modes of Hongyanhe Nuclear Power Plant,and output the power angle characteristic curve of nearby power plants.Through the simulation calculation of the actual power grid,the specific impact of Hongyanhe Nuclear Power Plant connected to the large power grid on the power angle stability of the transmission section in eastern Heilongjiang is verified.
