分布式光伏电站信息化运维的趋势分析

TREND ANALYSIS OF INFORMATION-BASED OPERATION AND MAINTENANCE OF DISTRIBUTED PV POWER STATIONS

针对分布式光伏电站存在运维管理难度大、运维成本高的问题,亟需通过信息化方式支持分布式光伏电站的运维工作,通过对此类光伏电站进行统一运行监控、调度指挥及数据管理,尽可能实现其全天候少人值守甚至是无人值守,并实时掌握光伏电站中各类设备的运行状态信息,保障设备安全,从而提高光伏电站运行的远程监控能力。针对分布式光伏电站传统运维方式中存在的不足进行了分析,并从4个方面分析了分布式光伏电站信息化运维方式。分析结果显示:通过合理而有效的光伏电站信息化运维方式,不仅能大幅缩短分布式光伏电站的巡检时间,精确判断和消除设备故障,而且可以较好地保证光伏电站的长期稳定运行和发电效益的最大化。

It is urgent to support the operation and maintenance of distributed PV power stations through information-based technology to address the difficulties and high costs of operation and maintenance management.By implement unified operation monitoring,scheduling command,and data management for such PV power stations,in order to achieve round the clock unmanned or even unmanned operation as much as possible,real-time grasp of the operation status information of various equipment in the PV power stations,ensure equipment safety,and improve the remote monitoring capability of PV power stations operation.This paper analyzes the shortcomings of traditional operation and maintenance methods for distributed PV power stations,and examines the ways in which distributed PV power stations can carry out information-based operation and maintenance from four aspects.The analysis results show that through the reasonable and effective information-based operation and maintenance methods of PV power stations,not only can the inspection time of distributed PV power stations be significantly shortened,equipment failures can be accurately judged and eliminated,but also the long-term stable operation and the maximization of power generation efficiency of PV power stations can be well ensured.
