Wind power plant centralized control center SCADA system based on CIM model

Abstract

The invention belongs to the technical field of power system new energy information management, and discloses a wind power plant centralized control center SCADA system based on a CIM model, and the system collects real-time data in a wind power plant, and stores the related data in a real-time database; stores description information and static information of a real-time database, and performs information management; storeshistorical data. The loading method of the real-time database comprises the step of loading the information of the real-time database by reading the related information ofthe database and the relationship among the databases. The wind power plant CIM modeling method is adopted, the wind power plant CIM model is established into the corresponding database model, fusionof the wind power plant and system power system resources is achieved, and analysis and calculation of a wind turbine generator are achieved. According to the invention, weight calculation is carriedout on parameters of the variable pitch system, and convenience is provided for fault diagnosis. Meanwhile, the wind power is predicted according to historical data and weather forecast, and the prediction result is relatively accurate.

Description

technical field [0001] The invention belongs to the technical field of information management, and in particular relates to a SCADA system of a wind farm centralized control center based on a CIM model. Background technique [0002] In recent years, the wind power industry has developed rapidly, the construction of wind farms has been accelerated, and the amount of power generated by wind energy has continued to increase. The development of wind power has brought both opportunities and challenges. Wind power companies have established a large number of wind farms in the same area, and there is a lack of unified management among multiple wind farms. There is a situation where the power grid cannot achieve unified dispatching of wind farms in the same area; wind farms increase, and wind turbines also increase. At present, there are hundreds of wind turbines in large wind farms. Due to the low energy density of the wind, there will be a certain distance between the wind turbine...

AI Technical Summary

Problems solved by technology

The development is accompanied by some problems: the current SCADA system cannot be integrated into the power system resources, and it is difficult to realize data sharing and exchange; the data interface standards of wind turbines from different manufacturers are different, and unified monitoring cannot be realized; the scalability of the wind farm SCADA system is poor. It is difficult to add the expansion part to the original SCADA system when the farm is expanded; it is difficult to predict and solve the faults of wind turbines, etc.

[0005] (1) The existing SCADA system cannot be integrated into the power resources, and it is difficult to realize the data exchange and sharing between the electric field and the power grid; the data interfaces of different manufacturers are different, and it is impossible to conduct unified monitoring of the wind turbines of different manufacturers in the wind farm; the SCADA system of the wind farm Poor scalability, it is difficult to add the expansion part to the original SCADA system when expanding the wind farm; it is difficult to predict and solve the failure of wind turbines

[0006] (2) There are too many collection points for wind turbines, and it is impossible to integrate wind farm system and power system resources, so that topology analysis and power flow calculation cannot be performed; it is difficult to add advanced applications of wind farms, and it is difficult to realize plug-and-play; the entire system of wind farms has data Redundancy; data transmission security

[0007] Difficulty in solving the above technical problems: the structure of wind turbines is complex, one wind turbine has more than 300 monitoring points, and each wind farm has hundreds of wind turbines

Moreover, each wind turbine will be started and stopped in the centralized control center, which is a great challenge for the remote monitoring system
