Abstract

The invention discloses a wind power comprehensive lightning protection monitoring method, which solves the problem that the current lightning protection detection method in the wind power field cannot accurately grasp the time, frequency and amplitude of lightning strikes suffered by a wind power generator in real time, and cannot efficiently perform fault early warning. The method of the present invention includes the following steps: S1: use the central controller configuration software to initialize and monitor the site, equipment, network information, touch screen calibration, lightning current acquisition module, SPD unit module, grounding resistance module, and connection resistance module of the lightning monitoring device Parameter setting; S2: Set parameters according to step S1 to continuously collect the lightning current information when the wind turbine blades, nacelle, and tower foundation are struck by lightning, the SPD status information of the wind turbine nacelle and tower foundation, the connection resistance of the carbon brushes in the nacelle, and the tower foundation The value of the grounding resistance; S3: According to step S2, read or transmit by connecting to the fan control system, the remote monitoring platform or the local connection terminal, and monitor, analyze and warn each measured value.

Description

technical field [0001] The invention relates to the technical field of wind power generator monitoring, in particular to a wind power comprehensive lightning protection monitoring method. Background technique [0002] Wind turbines are mostly located in areas where lightning strikes occur frequently, such as plateaus, mountains, and seasides. Due to their own characteristics, the probability of being struck by lightning is relatively high. With the increase of power generation and the rapid growth of the total installed capacity of wind power, the losses caused by lightning strikes to wind turbines cannot be ignored. However, current lightning protection detection methods and equipment in the field of wind power are designed specifically for wind turbines and cannot accurately grasp the time, frequency, and amplitude of lightning strikes on wind turbines in real time. The inability to efficiently carry out fault early warning has brought great inconvenience to our insurance...
