The invention relates to an in-place testing system of an AGC (automatic gain control) and AVC (automatic volume control) function of a wind power station and a realizing method thereof. The in-place testing system comprises a configuration background, an intelligent signal generator and a data acquisition unit which are connected; the configuration background is connected with the intelligent signal generator through a USB interface; the intelligent signal generator is connected with the data acquisition unit; the intelligent signal generator is connected with a wind power station booster station monitoring system or an AVC device of a wind power station device; and the wind power station booster station monitoring system is connected with a wind power generation unit energy management platform through a network interface. The in-place testing system disclosed by the invention has the advantages of complete functions and high automation degree, and integrates data acquiring, analyzing, processing and result-outputting in one body; and according to the relating method of the in-place testing system, disclosed by the invention, when a wind condition meets test requirements, a complete test period can be automatically finished by the in-place testing system without manual intervention.
Description
technical field [0001] The present invention relates to an on-site test system and its implementation method in the field of new energy access and control, in particular to a wind farm booster station monitoring system and an AVC (AutoVoltage Control) function on-site test system and its implementation method. Background technique [0002] In recent years, my country's wind power installed capacity has developed rapidly, and my country has become a big country in wind energy utilization and wind power installed capacity. However, traditional wind farms do not have the ability to automatically control active and reactive power, and the output of active and reactive power in wind farms is in a "free" state, with poor dispatchability. In order to meet the requirements of centralized wind power development, large capacity, and long-distance transmission, my country formulated the "Technical Regulations for Connecting Wind Farms to the Power Grid", and revised the grid-connected...
