黑龙江省电网负荷模型的在线测辨研究

通过对黑龙江省重要变电所各出线负荷的动态在线测量，得到了大量现场实测数据，经过参数辨识得到了各出线回路的负荷动态模型。对这些负荷模型参数进行了分析，与国内外同类负荷模型参数进行了研究，取得一些结果。利用实测的负荷数据对黑龙江省电网的暂态稳定进行了计算，并与原负荷模型的计算结果进行比较。这些动态负荷模型对于其它电网的运行分析都具有非常重要的价值。

Study on measurement and identification on-line of Heilongjiang grid load model

The dynamic load model of outgoing feeders in substation was given by identifying parameters, which were obtained from the actual datum measured dynamically on-line of the outgoing feeder loads of the main substation in Heilongjiang grid. Some results and conclusions were gained by having analyzed these parameters of the load model above, studied and compared them with the same load models in China and other foreign countries. The transient stability of Heilongjiang grid was estimated and calculated by using the actual load datum measured, which was compared with the results calculated out of the former load model. The dynamic load models will make much difference to other power grids in net operation analysis.
