Converter remote monitoring system used for wind power generation

Abstract

The invention relates to a converter remote monitoring system used for wind power generation, comprising a plurality of wind power generating sets. Each wind power generating set comprises a converter and a converter remote monitoring console which is provided with built-in converter monitoring software; and a converter monitoring network is formed by networking the converters, wherein the converter remote monitoring console and the converter monitoring network are in communication link. The system communicates with the converter remote monitoring console at the far end by the independent converter monitoring network, and the maintenance personnel directly monitor and maintain the converters and correlative systems so as to sufficiently utilize the data resources acquired and recorded by the converter; the selection of converter monitoring parameters is not restricted by the communication mode, the capacity and the communication protocol of a main controller, but depends on the communication mode, the capacity and the communication protocol of the converter monitoring network, thereby greatly improving the maintenance efficiency and quality of the wind power generating sets, shortening fault treatment time, realizing parametric analysis and fault prevention in daily operation, and obviously saving the maintenance cost.

Description

technical field [0001] The invention relates to a remote monitoring system, in particular to a remote monitoring system for a wind power converter. 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. Such as figure 1 As shown, the wind power generating set is mainly composed of a tower (not shown in the figure), a fan 1, a generator 2, a converter 3, a transformer 4, and a main controller 6. The core component is to realize the electrical parameter matching, energy conversion and real-time control between the generator 2 and the grid 5. The internal composition is complex, and intelligent control is generally adopted, and there are relatively many operating parameters....

AI Technical Summary

Problems solved by technology

[0005] 1. Since the main controller and converter used in wind power generation are generally from different manufacturers, the operating parameters of the converter collected by the main controller are often very limited due to the limitation of the communication mode, capacity and communication protocol of the main controller. And the real-time performance is also low. This monitoring method restricts the operation, maintenance and fault diagnosis of the converter and even the entire wind turbine;

[0006] 2. When a converter or related system fails, the information that the main controller can provide is extremely limited, and it is often necessary for the converter manufacturer to send personnel to the wind farm or even the site of the faulty wind turbine for fault analysis; Fields are generally distributed in relatively remote areas. This maintenance method will cause a lot of time and cost expenses, and because it belongs to post-processing, the maintenance quality will also be affected to a certain extent;

[0007] 3. On the other hand, the converter collects and records various operating parameters with high real-time performance and rich content including the power grid, converter, generator, etc., which has high monitoring and diagnostic value for the entire system. However, for a long time, the operating parameters collected and recorded by the converter have not been effectively monitored and utilized, resulting in low efficiency of wind farm monitoring
