Embodiment 1

[0055] like figure 2As shown, in order to briefly describe the content of the present invention, set and evaluate a certain wind farm event E, then perform step 200 to establish an event information database for E, set the benchmark evaluation library of the data management center to have no similar event evaluation, and establish This event has a single-level evaluation factor U. In this embodiment, single-layer factors are used to describe the evaluation process of the event. A specific wind farm event fuzzy comprehensive evaluation process is as follows:

[0056] 1. Execute step 201 to construct a fuzzy comprehensive evaluation index system:

[0057] First, step 211 is executed to target a certain wind farm event and establish an index U containing n single-layer evaluation factors, where u i (0≤i≤n) is an element belonging to the set U.

[0058] Next, execute step 212, establish the evaluation value set D of factor index U, and set a fuzzy comment set with 5 grades, a...

Embodiment 2

[0097] The analysis and decision-making event of the main controller hardware equipment maintenance of a wind farm is evaluated. image 3 There are three measures for the maintenance of the main control equipment: preventive maintenance, regular inspection and after-event repair are the implementation measures of the top-level evaluation goals.

[0098] First, establish the event information database for this evaluation, and search whether there are similar event evaluations of other wind farms in the data management center; If there is consistency in the indicators, then the historical evaluation results will be used as the data of this evaluation result. If there is no similar event evaluation or the evaluation factors are different, according to the principle of measurability and independence of the wind farm equipment maintenance evaluation index system, the historical operation data of the main controller components of the wind farm will be collected and included in the l...

Abstract

A wind power plant running monitoring and event comprehensive evaluation method includes the steps that firstly, a wind power plant class data management center is set up, and all event data of each wind power plant are collected and managed through event information bases, wherein each event information base comprises an evaluation index sub-base and a standard evaluation sub-base; secondly, wind power plant events are comprehensively evaluated, fuzzy comprehensive evaluation calculation is implemented for the wind power plant events containing multiple factors, and the evaluation results of the wind power plant events are outputted through weighted average fuzzy compositional operation; finally, the fuzzy comprehensive evaluation results are analyzed. The technical means for solving the wind power plant events is found, a decision-making means is provided for guiding an upper layer management mechanism to purposefully implement operation and maintenance management and take preventive measures, and on-site maintenance personnel can be assisted in accurately implementing on-site operation and maintenance work in place in a planned mode.

Description

technical field [0001] The invention relates to a method for monitoring the running state of large-scale and various types of wind power generating sets in multiple wind farms and a comprehensive evaluation method for wind farm events. Background technique [0002] Most of the existing wind farms in China generally have four main characteristics: multi-phase construction, large area, complex terrain conditions, different types and outputs of units in different regions in the same field, and different manufacturers of units in the same field. Therefore, most wind farms have which manufacturer's fan to use, and the monitoring system must be matched with the manufacturer's fan to monitor the operation of the fan. In this way, on the one hand, the communication protocol, communication mode and capacity of the main controller are different, and the operating status and key parameters of the electrical control system of the wind turbine cannot be monitored in real time, which not ...
