Embodiment Construction

[0014] The invention is applicable to the power grid with wind farm access and wide-area measurement system implemented. The wide-area wind power peak-shaving control system of the power system refers to the control system that is established and implemented in a wide area, based on the wide-area measurement system platform, and improves the peak-shaving capability of the system through the control of the wind farm to maintain or improve the stable operation of the power system. system. The wide-area wind power peak-shaving control system of the power system is generally built on the wide-area measurement system. Operation: PMU-Phasor Measurement Unit) Measure the voltage and current amplitude and phase angle of the sampling point in real time, and upload the measured data to the master station of the wide-area measurement system in real time; the master station of the wide-area measurement system receives and organizes each phasor The real-time data measured by the measureme...

Abstract

The invention discloses a peak regulating control system of wide area wind power in an electric power system, which comprises a system architecture of the peak regulating control system of wide area wind power unified in the whole network based on wide area measurement system (WAMS), a control signal selection of the peak regulating control system of wide area wind power, a control strategy of the peak regulating control system of wide area wind power and a controlling communication interfacing technology of the peak regulating control system of wide area wind power. The method belongs to the technical field of electric power system wide area control; a technical proposal of the invention can be used for solving the difficult problem that the electric system lacks the peak regulating control system of wide area wind power unified in the whole network; the constructed system is used as a new method of peak regulation when the peak regulating capacity of hydroelectric generating units and thermal power generating units is exhausted, can increase the peak regulating ability of grid and promote the security and stability level of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power system wide-area control, and in particular relates to a power system wide-area wind power peak regulation control technology. Background technique [0002] With the development of my country's wind power technology and the emphasis on the development and utilization of renewable energy, wind power has developed rapidly in my country in recent years. At the same time, the impact on the system brought about by the wind power grid connection has also begun to appear in several wind power provinces such as Heilongjiang, Liaoning, Jilin, Inner Mongolia, and Gansu. Allocation brings increasing difficulties. Large-scale wind power access has brought new challenges to the system in terms of peak shaving capability, section limitation, line carrying capacity, and voltage stability. There is an urgent need to develop a reasonable and effective wide-area wind power peak shaving control system. to improve sy...
