摘　　要：为保证国家电网公司750kV示范工程1500MVA满负荷试验顺利进行,利用BPA程序计算750kV示范工程1500MVA试验方式下的系统稳定性;提出在公伯峡电厂1～5号发电机励磁系统配置电力系统稳定器(power system stabilizer,PSS)改进系统阻尼;分析发电机自并励系统对系统稳定影响的原理以及公伯峡电厂1～5号发电机PSS参数整定试验结果,并用BPA程序重新对公伯峡电厂发电机配置PSS参数后的试验系统进行了稳定计算分析,结果表明试验系统静态稳定极限大于1800MW,为1500MVA满负荷试验提供了技术保证;最后给出了750kV示范工程1500MVA满负荷试验分析结论。To ensure the implementation of 1 500 MVA full-load test of 750 kV power transmission and transformation pilot project belonging to State Grid Corporation of China （SGCC） without a bitch, the system stability of 750 kV power transmission and transformation pilot project under 1500MVA full-load test is calculated by BPA program; it is put forward that to improve system damping, power system stabilizers （PSSs） should be configured in excitation systems for generators from No. 1 to No. 5 in Gongboxia power station; the principle of generator excitation system＇s impact on system stability and the test results of PSS parameter setting of generators from No.1 to No.5 in Gongboxia power station are analyzed, and by use of BPA program the calculation and analysis of the stability of the test system are anew conducted while the PSS parameters are configured to the generators in Gongboxia power station, calculation and analysis results show that the steady state stability limit of the test system is higher than 1800 MW, thus the technical assurance for 1500 MVA full-load test of 750 kV power transmission and transformation pilot project is provided. Finally, the analysis and conclusion of 1500 MVA full-load test of 750 kV power transmission and transformation pilot project are given.
