Fan electric control system and fan converter integrated control topology

Abstract

The invention discloses a fan electric control system and fan converter integrated control topology which mainly comprises a main controller, a fan converter cabinet and a fan electric control system and realizes that control functions of an electric control system and a converter are integrated into the main controller, so that programs are integrated on the main controller, development platform and integrated control are unified, the problem of matching and customizing of multiple controllers and interfaces thereof is solved, the docking time is shortened, development of products is accelerated; and a tower foundation electric controller and fan converter cabinet integrated structure layout is simple in assembly, is easy to construct, and can be used for saving unnecessary cost for a fan host operator.

Description

【Technical field】 [0001] The invention relates to a wind power generating set, in particular to an integrated control topology of a wind turbine electric control system and a wind turbine converter. 【Background technique】 [0002] In wind turbines, two key devices, the wind turbine electrical control system and the wind turbine converter, are used. Currently, the wind turbine electrical control system and the wind turbine converter are produced by different manufacturers, and separate control is required. The manufacturers supplying and providing services are different, and both the host side and the converter side of the wind turbine are technically highly confidential. Both parties are cautious and conservative in the process of technical negotiations. After a long run-in period, the test period in the later period is also very long; the discrete control requires a two-level or multi-level control system, which has high cost, complicated control, and lack of systematicness...

[0002] In wind turbines, two key devices, the wind turbine electrical control system and the wind turbine converter, are used. At present, the wind turbine electrical control system and the wind turbine converter are produced by different manufacturers, and separate control is required. The manufacturers supplying and providing services are different, and both the host side and the converter side of the wind turbine are technically highly confidential. After a long run-in period, the test period in the later period is also very long; the discrete control requires a two-level or multi-level control system, which has high cost, complicated control, and lack of systematicness; The equipment of the wind turbine converter is not strongly related, scattered layout, large footprint, multiple construction and assembly time-consuming, increasing labor costs; multi-platform development, poor transparency, when a problem occurs, multi-party contact is required to improve the efficiency of problem solving It also needs to invest a lot of manpower, material resources and financial resources to solve the existing problems of their own development, testing and industrialization, which increases the operating cost of the main engine of the wind turbine and increases the management difficulty of the main engine operator of the wind turbine.
