摘　　要：国家电网公司750kV输变电示范工程已安全稳定运行近1a,为进一步检验示范工程的设计、施工、试验等方面的质量和效果,全面做好工程后评估工作,通过系统计算确定了以公伯峡电厂5台300MW机组为电源的试验方案,并改造投运了公伯峡电厂机组的电力系统稳定器,制定了完备的试验方案和反事故预案,开展了示范工程1500MVA负荷试验,测试了示范工程的环境数据和设备温升数据,结果表明,示范工程环保数据满足国家环境保护要求,满负荷试验后所有设备正常,示范工程能够满负荷运行。Since Sept. 26, 2005 the 750kV transmission and transformation pilot project of State Grid Corporation of China has operated securely and stably. To further validate the quality and effect in design, execution and tests of this pilot project as well as to overall evaluate this engineering, by means of power grid calculation a test scheme was decided in which five 300MW units in Gongboxia power plant were chosen as power source of the test, the power system stabilizers of generation units in Gongboxia power plant were renovated and put into operation, correspondingly, a complete test scheme and accident prevention program were drafted. Based on the preparation, on Sept. 1st, 2006 the rated load test for the pilot project was carried out, the environmental data and temperature rise data of equipments were measured during the test. Test results showed that the environmental data of the pilot project satisfied the requirement of national environmental protection standard, after the test all equipments operate normally and the pilot project can operate at full load.
