摘要
基于地区电网辐射运行特点,提出了分层分区的电压无功控制方案。在实时动态分区的基础上,采用了区域电压控制与变电站电压校正控制相结合的协同控制方案,在保证母线电压合格的前提下,减少设备震荡带来的效率低、能耗高等问题。面向不同分区提出了针对性的无功控制策略,如关口无功控制、单站无功控制、主变无功控制等。在无功控制时对电容器进行排序,并根据电容器预判结果决定需要切除或投入的电容器的容量,保证在系统电压合格的前提下最大程度上减少系统网损。
Based on the radiation operation characteristics of the regional power grid,a hierarchical and zoned voltage and reactive power control scheme is proposed.Based on real-time dynamic zoning,a cooperative control scheme combining regional voltage control and substation voltage correction control was adopted.On the premise of ensuring the qualified busbar voltage,problems such as low efficiency and high energy consumption caused by equipment oscillation were reduced.Targeted reactive power control strategies have been proposed for different zones,such as gateway reactive power control,single-station reactive power control,and main transformer reactive power control,etc.During reactive power control,capacitors are sorted,and the capacity of capacitors that need to be disconnected or put into operation is determined based on the predicted results of the capacitors to ensure that the system network loss is minimized to the greatest extent under the premise that the system voltage is qualified.
