Self-consuming software metering method of wind generating set

Abstract

The invention discloses a self-consuming software metering method of a wind generating set. The self-consuming software metering method comprises the following steps: 1) measuring equipment power gridvoltage; 2) carrying out current measurement; 3) setting an equipment running state flag bit, namely a working flag bit; 4) obtaining total self-consuming power of the unit equipment; 5) obtaining energy consumption of unit equipment; 6) carrying out self-consuming test and calibration; and 7) carrying out parameter curing; according to the method, a traditional hardware measurement mode can be well replaced, the unit self-consumption metering work is achieved through a software algorithm, and the unit self-consumption is reduced by monitoring the state of each component and the self-consumption situation, optimizing the component starting and stopping logic and reducing the unit self-consumption.

Description

technical field [0001] The present invention relates to the technical field of wind power generators, in particular to a self-consumption software measurement method of wind power generators. Background technique [0002] At present, wind turbines need to use hardware (voltage sensors and current transformers connected to the power measurement module) to measure the power generation of the unit to measure the total power consumption, but it is impossible to know the self-consumption of each component of the unit. If you want to measure the self-consumption power of each component device, you need to add corresponding sensors, which is very costly and difficult to implement. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies and shortcomings of the prior art, and propose a self-consumption software measurement method for wind power generating sets, which can well replace the traditional hardware measurement method, and re...
