为了获得水轮发电机组惯性时间常数,笔者提出采用现场甩负荷试验实测数据计算惯性时间常数的方法,阐述惯性时间常数的物理意义,介绍惯性时间常数计算原理和计算方法,并对计算结果进行分析,总结出影响惯性时间常数的因素.结果表明:采用甩负荷试验测取数据计算得到的水轮发电机组惯性时间常数能反映正常运行工况的真实值.
Calculation of Inertia Time Constant for Hydroelectric Sets
In order to obtain the inertia time constant of hydroelectric set,the authors put forward the method of calculating the inertia time constant by using the measured data of field load rejection test,expound the physical significance of the inertia time constant,introduce the calculation principle and calculation method of the inertia time constant,analyze the calculation results,and summarize the factors affecting the inertia time constant.The results show that the inertia time constant of the hydroelectric set calculated by the data measured by the load rejection test can reflect the real value of the normal operating conditions.
