调度侧风电功率预测系统设计与应用

摘要

为解决风电场功率预测数据异常和数据丢失的问题,提出了一种调度侧风电功率预测系统方案.调度侧风电功率预测系统由数值天气预报下载服务器、反向物理隔离装置、数据采集与处理服务器、预测系统数据库服务器和功率预测应用服务器构成.通过在云南大理电网的应用结果表明:调度侧风电功率预测系统与发电侧风电功率预测数据相互校核,互为备用,进一步提高了全网预测精度,保障了电网的安全运行;系统效果良好,安全性高,实用性强.%In order to address the prediction data anomaly and data loss in wind farms,a scheme of wind power forecasting system at the dispatching center is proposed in this paper.The wind power prediction system at the dispatching center consists of numerical weather forecasting server,reverse physical isolation device,data acquisition and processing server,prediction system database server and power prediction application server The wind power forecasting system at the dispatching center and the wind power forecasting data at the generating station are mutually checked to further improve the forecasting accuracy and ensure the safe operation of the grid.The system is now in operation in Yunnan Dali grid.
