摘　　要：对湛江电厂东汽型300MW机组成功实施常规法和测功法两种甩电荷试验的技术特点和试验结果进行评述,指出现代大型机组调节系统由于OPC的存在,甩负荷后转子的飞升特性与调节系统的静态特性关系不大。而测功法甩负荷试验实际上仅是对OPC功能快速性和可靠性的验证,一些常规法甩负荷试验的优点是无法代替的。Some technique features and their test results of two load rejection tess were commented by means of carrying out conventional rejection test and using dynamometry on Dongfang turbine works 300MW unit in Zhanjiang power plant. In the modern large size power turbine governing system, the rotor raising character while load rejection almost has nothing to do with the static characteristics of governing system by reason of OPC existing, while load rejection using dynamometry only to validate the rapidity and reliability of OPC function. Some advantages of conventional rejection test can not be substituted by dynamometry.
