Wind power plant point table rechecking method and device based on SCADA system

Abstract

The invention relates to a wind power plant point table rechecking method and device based on an SCADA system. The method comprises the following steps: acquiring a controller point table of each wind turbine generator, and extracting actual information of acquisition points; acquiring a point table configuration file of the SCADA system, and extracting acquisition point configuration information; establishing a mapping model according to the acquisition point configuration information; comparing the actual information of the acquisition point with the configuration information of the acquisition point through the mapping model; and outputting the difference between the actual information of the acquisition point and the configuration information of the acquisition point. According to the scheme provided by the invention, the configuration file of the SCADA system and the controller point table of the wind turbine generator can be automatically rechecked to replace long manual rechecking work, so that the time required by the rechecking work is greatly shortened, and the efficiency of the point table rechecking work is improved; errors caused by a large number of point tables in a manual rechecking process are avoided, errors existing in the rechecking process are effectively reduced, and the point table rechecking accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of wind power generation, in particular to a SCADA system-based method and device for reviewing wind farm point tables. Background technique [0002] my country is the world's largest energy consumer. The energy structure has been dominated by coal for a long time. The energy demand has shown a rapid growth trend. The dependence on foreign oil and gas continues to increase. The task of promoting energy transformation is very urgent. The Chinese government has introduced a series of policies to actively support energy transition. With the continuous development of the wind power industry, wind farms are no longer built with a single type of wind turbine. In order to adapt to the calibration limit of the rated capacity of wind farms, it will soon become an inevitable trend to build wind farms with multiple types of wind turbines. [0003] At present, one of the functions of the wind farm SCADA syst...

Problems solved by technology

The process of configuring the point table includes many times of manual review process. Due to the large number of point tables, many monitoring point names are relatively similar, and errors will inevitably occur during the verification process. If the wrong point table is directly used in the SCADA system of the wind farm, it will be Some monitoring points will not be collected or stored, which will directly affect the normal monitoring of wind turbines and the data collection of wind turbine operation data analysis

The conventional method wastes manpower and is inefficient, and the result of point table configuration review is still not guaranteed
