METHOD FOR CONFIGURING REACTIVE COMPENSATION DEVICE OF LARGE-SCALE WIND POWER TRANSMISSION SYSTEM

摘要

The present invention belongs to the field of electric power systems, and in particular, relates to an application solution for a reactive compensation device of a large-scale wind power transmission system. Aiming at a large-scale wind power transmission system, taking the satisfaction of the demand for power transmission and wind power integration as an objective, and by means of the reactive balance analysis under different operation modes in different level years, proposed are capacitive and inductive reactive demands of each transformer station in the system, and also proposed is a configuration solution of a low-voltage side fixed switching reactive compensation device such as a capacitor, a reactor and the like, and a dynamic reactive compensation device such as a controllable reactor, a static reactive compensator and the like. The proposed configuration solution can ensure that the voltage at each point of the system is controlled within a reasonable range under different operation modes, while a dynamic reactive compensation device can satisfy the reactive control requirements for the grid voltage during wind power fluctuations, and has a very strong engineering adaptability.
