Abstract

The invention, which belongs to the technical field of the power, especially relates to a wind power plant energy storage testing system and evaluation method. According to the invention, an outgoing line is arranged at the main transformation high-voltage side of the wind power plant and a bus is arranged at the low-voltage side; and incoming lines of all fan current collection circuits, a wind power plant passive compensation device, and an energy storage device. With the system and the method, the performance of the energy storage device can be effectively detected and the improvement effect of the wind power plant stability can be verified. Moreover, the workload is simplified; the operation is simple, flexible, and convenient; the processing capability is high; the data processing becomes flexible; the testing method is simple and practical; the collected data quantity is small; and the capability of image outputting is realized. In addition, a favorable external data interface can be provided; and the testing result analysis can provide comprehensive evaluation for the performance of the energy storage device. Therefore, the provided system and method are suitable for the performance testing analysis of the energy storage device arranged at the wind power plant.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a wind farm energy storage test system and an evaluation method. Background technique [0002] Wind energy is an intermittent energy source, and there are certain errors in wind speed prediction. Therefore, wind farms cannot provide continuous and stable power, and the stability of power generation is poor. More and more large and medium-sized wind farms are put into operation, and are generally directly connected to the transmission grid. The power fluctuation of wind farms will affect the power quality of the local power grid, resulting in voltage fluctuations and flicker. Therefore, the power grid has higher and higher requirements for wind power quality. . The development of battery technology and power electronics technology has promoted the application of battery energy storage devices in power systems. Combining energy storage devices with wind power ge...
