摘　　要：并网原动机及调速器的运行特性,直接关系到机组对电网指令及在电网波动情况下的响应能力,进一步影响到供电品质和电网运行安全稳定。建立原动机和调速器数学模型以用于电网稳定分析是十分重要的。鉴此,介绍了我国原动机及调速器建模与参数测试工作的现状,结合广东及南方区域具体情况,讨论BPA程序局限、控制系统模型、燃气-蒸汽联合循环模型及模型验证等问题,并展望建模与参数测试的工作方向。The operational characteristics of the prime mover and its governor in grid can determine straight their ability of responding to the grid commands and power fluctuations, and thus affect the power supply quality and the grid security and stability. It is important to build models of the prime mover and its governor for power system stability analysis. The status is introduced of the modeling and parameter testing on prime mover and its governor in China. The issues of BPA program limitation, control system model, gas-steam combined cycle model, model verification are discussed combined with the specific circumstances in Guangdong and other southern regions, and the prospect of modeling and parameter testing is predicted.
