摘要

针对传统方法在评价风电场运维水平时仅考虑可利用率数量不注重品质的问题

本文在《风力发电设备可靠性评价规程》定义的可利用率指标的基础上

结合风能随时间变化的影响

提出风能可利用率指标和可利用率品质指标的定义和计算方法

综合评估风电场在检修维护计划制定、故障早期预警及处理、备品备件管理以及风电场天气跟踪等方面的整体运维效果

适应了风能不可控、不可调的特点。该评价方法已在华能新能源公司86个风电场的在线运维评估中应用

应用结果表明该方法快捷高效

可准确评价风机、风电场及区域公司的运维水平。

Abstract

When evaluating the operation and maintenance level of wind farm

the conventional method only considers the quantity of availability and pays no attention to the quality. To solve this problem

this paper proposes the definition and calculation method for the wind energy availability index and availability quality index

on the basis of the availability rate defined in Rules for Reliability Evaluation of Wind Power Equipment

and combining with the effect of wind energy distribution over time. This method comprehensively evaluates the overall operation and maintenance effect of the wind farm from the aspects of maintenance plan formulation

fault early warning and treatment

spare parts management and wind farm weather tracking

which adapts to the wind energy's characteristics of non-controllable. Moreover

this method has been applied in evaluation of operation and maintenance of 86 wind farms of Huaneng Renewables Corporation

and the results proved that it is accurate and efficient

which can accurately evaluate the operation and maintenance level of fans

wind farms and regional companies.
