天津电网负荷模型及适应参数

摘要

Proper modeling of the power load is a crucialfactor, sometimes even a deciding factor, influencing the results of the simulation computation of power system. Based on the actual conditions of Tianjin power grid, this paper proposes to build the Tianjin power gnd load model in the frameworks of Synthesize Load model (SLM). In line with the concept of LOADSYN and by means of comprehensive statistics, studies on the load model and relevant parameters are conducted to obtain the model parameters of all kinds of typical load systems of Tianjin power grid. These parameters are applied in the calibration of grid safety, and help identify and eradicate the hidden faults in the grid.%负荷模型建立的恰当与否往往对电力系统仿真计算结果产生重要影响,有时甚至是质的结论性的影响.结合天津电网实际,提出在采用综合负荷模型(SLM)框架下构造天津电网自身的负荷模型.依据LOADSYN思想,使用综合统计法.开展了天津电网负荷模型及相应参数研究,获得了天津电网各类典型负荷系统的模型参数,并应用于电网的安全校验,发现和解决了天津电网存在的安全隐患.
