摘　　要：在简要介绍山西阳城电厂至江苏淮阴 5 0 0 k V输变电工程概况的基础上 ,首先对该工程已采用的固定串补方案作综合研究。利用德国西门子公司开发研制的电力系统仿真软件 NETOMAC,以 2 0 0 5年华东福建联合电网为研究对象进行了阳城送出的稳定计算 ,并对计算网络进行了等值简化。通过等值前后系统动态特性的比较 ,验证了等值网络对于阳城送出稳定问题研究的有效性。针对阳城—淮阴 5 0 0 k V送出一期工程采用固定串补方案后系统仍存在较严重的暂态稳定问题 ,再对采用可控串补方案作可行性的研究。在现有参数的条件下 ,对可控串补方案作初步的设计 ,机电和电磁暂态模式下的 NETOMAC数字仿真 。The Y H 500 kV Transmission project-Yangcheng Power Plant to Huaiying(a spot of ECPN is briefly described.The FSC plan used by the project has been firstly studied.Using the East China-Fujian Consolidated Grid in 2005 as a study object,The stability computation of Yangcheng output has been carried out utilizing Siemens′ NETOMAC power system simulation software and the equivalent simplification of the computed network has been then carried out.The effectiveness of the equivalent network for the study of stability problem of the Yangcheng output has been testified.Due to the serious transient stability problem will be still existed after using FSC,and the feasibity study on the pln of TSCS is then carried out.A Preliminary design for TSCS plan and a NETOMAC digital simulation under electro magnetic transient state mode has been made and a comparison with the FSC plan bas been also worked out.
