摘　　要：介绍了采用国际著名电磁暂态仿真软件PSCAD/EMTDC对多机系统次同步谐振进行分析时主要用到的两种方法:基于时域仿真实现的复转矩系数法—测试信号法,时域仿真法。对于多机系统应用PSCAD/EMTDC进行SSR分析时,针对同型同负载、同型不同负载多机系统以及不同型多机系统等情况,分别可以采用相应分析方法,以达到预想的效果;将两种分析方法各自的优、缺点进行了分析对比。The two methods, the complex torque coefficient method realized by time-domain simulation method--the test signal method and the time-domain simulation method, which are used to analyze the subsynchronous resonance （SSR） for multi-machine systems with the help of the well-known electromagnetic transient simulation software PSCAD/EMTDC are recommended＋ When the PSCAD/EMTDC is adopted to conduct SSR analysis, in order to achieve the expected results, relevant analytic method can be used for multi-machine systems with identical units and equal loads, or with identical units but unequal loads, or with no-identical units. The merits and demerits of each analytic method are analyzed and compared.
