Wind field battery testing intelligent distribution method

Abstract

The invention discloses a wind field battery testing intelligent distribution method. A communication command used for transmitting battery detection and distribution is additionally arranged between a draught fan master control system and a wind field monitoring system. The communication command completing steps include that the draught fan master control system transmits an information that a draught fan has been ready to battery testing to the wind field monitoring system; after the wind field monitoring system collects state information transmitted by the draught fan master control system, a command that grid disconnection is allowed for conducting variable pitch battery detection is issued to the draught fan after operation is carried out; the draught fan receiving the command issued by the wind field monitoring system starts to execute the variable pitch battery detection procedure, and normal starting and synchronization are achieved after battery detection is completed. According to the wind field battery testing intelligent distribution method, draught fan batch grid disconnection caused when the wind field draught fan conducts the variable pitch battery detection can be avoided, and the stability of wind field power grids is maintained. The wind field battery testing intelligent distribution method is simple and practicable, any improvement on hardware is avoided, any modification on control logics of a draught fan controller can be avoided, only one communication mark needs to be additionally arranged, and all configurations can be completed in a monitoring chamber.

Description

technical field [0001] The invention relates to the problem of battery detection in wind farms recently, in particular to an intelligent distribution method for battery detection in wind farms. Background technique [0002] With the relaxation of the country's policy on wind power generation, more and more wind power plants have appeared on the land of China. Each wind farm has multiple wind turbines, ranging from dozens to hundreds. It puts forward higher and higher requirements for the batch control of fans. [0003] The current wind power generators are prone to downtime accidents caused by batteries during work and movement. In terms of maintaining the stability of the power grid, in recent years, there have been more and more requirements for the transformation of wind farms to maintain the stability of the power grid. Requirements including power grid transformation, reactive power management, active power management, and low-voltage ride-through are all required to m...
