Wind turbine running simulation system based on PLC (programmable logic controller) system

Abstract

The invention discloses a wind turbine running simulation system based on a PLC system, comprising a wind turbine simulation system and a wind turbine main control system that is connected with the wind turbine simulation system and is to be tested. The wind turbine running simulation system is characterized in that the wind turbine simulation system comprises an SCADA (Supervisory Control and Data Acquisition) system and a wind turbine simulation PLC, wherein the wind turbine simulation PLC and the wind turbine main control system carry out data interaction; and a PLC development tool can provide a programming language development and simulation program of IEC61131-3. In the invention, the wind turbine simulation system established based on the PLC system can effectively support the simulation test during the early stage and intermediate or latter stage of the research and development of the wind turbine main control system, and has the advantages of small land-occupied area and low cost.

Description

technical field [0001] The invention mainly utilizes the PLC system to quickly construct a wind power simulation system, utilizes the IO channel of the PLC to realize the simulation of all measuring point signals on site, and is used for the simulation debugging of the wind power main control system. Background technique [0002] At present, wind power is developing rapidly in our country, and the installed capacity is rising rapidly, but the core wind power master control system of wind power is basically monopolized by imported manufacturers. At present, the number of domestic manufacturers developing independent wind power master control systems is also increasing. As a new system, it needs to be fully verified in the laboratory before it is actually put into on-site trial operation. The current laboratory verification methods mainly include the following types: [0003] 1. Use simulation software to simulate the control strategy. For example, using Matlab or Blade for ...

AI Technical Summary

Problems solved by technology

Since the generator and converter are all real objects, there is no modeling link, and the method can effectively simulate the entire wind power main control system. The disadvantages are that it occupies a large area, the cost is extremely high, and it is not easy to change the capacity of different units. The corresponding parameters in the case are limited by the speed regulation capability of the prime mover, and it is not easy to simulate the influence of various rapidly changing wind speeds
