基于可靠性和发电性能的新能源发电设备状态评估方法

与传统火电机组不同,新能源发电设备单机容量小,单机停运不会对新能源电站的供电可靠性产生明显影响,因此对新能源发电设备关注可靠性的同时,更应该关注设备的发电性能。为此提出了一种基于可靠性和发电性能双重指标维度的新能源发电设备状态评估方法,提出了发电性能关键指标的计算方法和数据源标准化要求。将该方法在国家风光储输示范工程进行评价应用,通过评估结果数据分析,总结出了新能源发电设备发电性能指标的推荐阈值。所提出的方法能够为新能源发电设备状态评估提供一种新的技术手段。

Condition Assessment Method of Renewable Energy Generation Equipment Based on Reliability and Generation Performance Indicators

Compared with the conventional thermal power generator units, the renewable energy power generator is small in unit capacity and has little impact on the reliability of a renewable energy power station when a single turbine ceases to operate. It is therefore imperative to pay more attention to the power generation performance of the renewable energy generation equipment in addition to the reliability. A novel condition assessment method is developed in this paper for renewable energy power generation equipment based on the indicators of reliability and power generation performance. And the calculation methodology for the key power generation performance indicators and the requirements for data source standardization are proposed. The proposed condition assessment method has been applied in a national demonstration project of wind power, PV power, energy storage and power transmission to evaluate the condition of generation equipment. Through analyzing the assessment results, the recommended threshold of power generation performance indicators are presented. This method can provide a new technical approach to evaluate the condition of the renewable energy generation equipment.
