[0018] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] like figure 1 As shown, the present invention provides a method for locating power grid frequency disturbance source oriented to the dispatching master station, comprising the following steps:
[0020] A: Use the existing WAMS data acquisition system to obtain the system frequency and power plant unit power in the whole region, and form a system frequency and power plant unit power parameter library. Among them, the data collected by WAMS needs to be obtained through the data interface, and the system frequency is the unified frequency in the power grid , the unit power of the power plant comes from the units under all power plants in the system collected by the PMU, and the data are millisecond-level real-time data;
[0021] B: According to the system frequency data obtained in step A, determine the analysis ...
