应用电网运行大数据分析实现无功电压精准控制

Reactive Voltage Precise Control Implement with Big Data Analysis of Power Grid Operation

针对无功电压管理现状和自动电压控制(AVC)系统运行期间出现的问题,通过创新指标评价体系,开展系统在线诊断评估,应用大数据分析,协同三级调度管理,利用优化AVC控制策略、增加风火协调控制、强化缺陷闭环管控、加强电压监控调整、合理调整运行方式等手段,从管理手段和技术措施两方面入手,有效提升了无功电压管理水平,实现了无功电压分时分站精准控制。

In allusion to the problems existing in the current management situation of reactive voltage and during the system operation of automatic voltage control(AVC),this paper used the innovated index system to carry out online evaluation,applied big data analysis and cooperated with three-level dispatching management,by optimizing AVC control strategy,increasing the coordination control between wind power and thermal power,intensifying defects closed loop control,reinforcing voltage monitoring adjustment and adjusting reasonable operation mode etc methods.From the respects of management tools and technical measures,the system improved the management level of reactive voltage,realizing the time-sharing and substation-sharing precise control of reactive voltage
