Abstract

The invention discloses a site detection system and method for power grid adaptability of a master control system of a wind power generator set. The detection system comprises a first bus, a bypass line, a main loop, a second bus and three impedance voltage-division circuits. In the detection system, the detection system is a low-voltage device and is convenient to move and transmit, the power grid adaptability experiments of a plurality of wind power generator sets can be developed within short time, and the detection system is suitably used for effect estimation after a draught fan in a windfield is transformed and the draught fan is casually inspected.

Description

technical field [0001] The present application relates to the technical field of wind turbines, in particular to a system and method for on-site detection of grid adaptability of the main control system of wind turbines. Background technique [0002] At present, a 35kV mobile power grid adaptability detection platform has been developed, and the detection platform has carried out many field tests. figure 1 It is the usage scenario of the detection platform 9 in the prior art. The following problems were found in the field test: 1. The first test of the randomized wind turbines could not meet the requirements of the wind turbine grid-connected ability test standard, and the manufacturer had to perform multiple component replacements and software changes to complete the test. 2. The power grid adaptability testing platform consists of two containers (each container is about 35 tons). Each test requires the hoisting and transportation of the container and the dragging and inst...
