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.
