| 摘 要： | 新能源场站的大规模集群化接入不仅增加了连锁故障的发生概率,也恶化了故障发生后的电网运行状态。为适应电网运行分析的新要求,以新能源机组和无功补偿装置实际运行工况为依据,研究了一种用于预测新能源场群连锁故障路径的仿真计算方法。通过基于大电网数据的仿真算例分析,得到了某新能源场群在典型约束条件下的详细连锁故障路径。结果表明:基于新能源场站机组实际情况建立的仿真模型更适宜于连锁脱网路径的仿真预测。

| Abstract: | New energy power stations on a large scale clustering to connect to power grid, not onlyincreases the probability of cascading failure, but also deteriorates the power grid operation status after failures. Considering the new requirements of the power grid operation analysis, based onrunning conditions of new energy units and reactive power compensation devices, researches asimulation method using to forecast cascading failure path of new energy power station groups.Through the simulation calculation example analysis based on the large power grid data, acquires the detailed cascading failure path of a certain new energy power station under the typical constraintcondition. The researche result shows that: the simulation model based on actual condition of newenergy units, suits simulation forecast for cascading off -line failure path of new energy powerstation groups. |
