A wind farm real-time monitoring system and monitoring method

Abstract

The invention discloses a wind power plant real-time monitoring system. The wind power plant real-time monitoring system comprises a plurality of wind generating sets and a current transformer centralized maintenance and monitoring device. Each wind generating set comprises an electric generator, a current transformer and a fan master control which are sequentially connected. Each of the current transformers and the fan master controls in the wind generating sets comprises a first working control port and a second high-speed port. The current transformers are in working control connection with the first ports of the fan master controls through the first ports of the current transformers; the current transformers are in maintenance monitoring connection with the second ports of the fan master controls through the second ports of the current transformers; the wind generating sets are connected with the current transformer centralized maintenance and monitoring device through networking of the fan mater controls of the wind generating sets; the current transformer centralized maintenance and monitoring device analyzes and processes real-time information and basic information of the current transformers of the wind generating sets. According to the wind power plant real-time monitoring system, the current transformers of the wind generating sets are monitored by utilizing an existing wind power plant local area network, networking is easy, the information comprehensive utilization efficiency of the fan mater controls and the current transformers is high, a wind power plant can be conveniently and deeply monitored and maintained in time, and the maintenance cost is obviously saved.

Description

technical field [0001] The invention relates to a real-time monitoring system for the operation of a wind farm, and also relates to a method for real-time monitoring of the operation of the wind farm. Background technique [0002] As a new energy source that is clean, renewable and has great potential, wind power has been developing rapidly all over the world. Wind power generation is limited by the utilization efficiency of wind energy and the capacity of a single machine, and dozens to hundreds of wind power generators need to be arranged in a wind farm. Wind turbines can be doubly-fed or full-power. Such as figure 1 As shown, the wind power generating set 100 is mainly composed of a tower (not shown in the figure), a wind turbine 1, a generator 2, a converter 3, a transformer 4, a wind turbine master control 6, and a pitch control device 7, etc. The controller 6 is generally responsible for the overall control of the wind turbine, especially the coordination of the con...
