摘要
介绍了国内外基于事故仿真的负荷建模方法的研究现状和应用情况;对东北电网三相短路试验和负荷建模研究方法进行了系统的介绍和总结,包括:试验方案的研究和编制,试验和研究步骤及整个试验研究过程包含的内容和采用的方法,采用的事故仿真和实测数据一致性判别原则,各种参数对仿真结果的影响程度。对通过试验仿真得到的负荷模型的非唯一性和机理分析的必要性进行了分析论证。
Present situation of research and application of load modeling methods based on fault validation home and abroad is presented. Systemic presentation and summation of both appfied load modeling approaches and three-phase shortcircuit tests carried out in Northeast China power grid are given, including the research and compiling of test scheme, the procedures for the tests and research, the contents of the whole experimental investigation and adopted methods, the principle to judge the consistency between the data from fault validation and practical measurement respectively as well as the influencing extent of various parameters on simulation results. The non-uniqueness of the load model obtained by tests and simulations and the necessity to perform mechanism analysis are researched and demonstrated.
