计及冷负荷恢复特性的单节点最大负荷恢复量计算
|
摘要
大规模恢复负荷、减小停电损失是电力系统恢复的主要目标。本文根据环境温度、停电时间和温控负荷比例3个因素对冷负荷恢复的影响,提出一种冷负荷恢复量的计算模型。结合用电主体、负荷启动特性等两种母线负荷分类方式,并计及包括暂态频率在内的实际约束建立了以节点负荷恢复量最大为目标的通用模型。通过增广潮流计算、暂态能量函数计算及电力系统分析软件PSD-BPA仿真对负荷恢复的稳态、暂态过程进行详细校核。新英格兰10机39节点系统算例验证了所提方法的合理性和有效性。
The target of power system restoration is to restore large-scale load and reduce power outage loss.According to the influence of such three factors as environment temperature,power outage time and temperature controlled load proportion on the cold load pickup,the model for calculating restoration amount of cold load is established.The generalized model of load restoration with the objective of maximizing the recoverable load amount and the practical constraints of transient frequency is established by combining two types of bus load classification which are electricity body and start-up characteristics of load.The steady state and transient state process of load restoration are studied by the expanded flow calculation,transient energy function calculation and power system analysis software PSD-BPA simulation.The New England 10-generator 39-bus power system is used as an example to validate the reasonableness and effectiveness of the proposed method.
