主动配电网过渡期的自适应双重电压控制方法

Adaptive Dual Voltage Control Method for Active Distribution Network in Transition Period

针对现有配电网无功电压控制方法既暂时无法实现区域协同控制,又不满足于传统控制方法效果的现状,本文基于配电网不同发展阶段的无功电压特性及需求分析,提出一种适用于主动配电网过渡期的自适应双重电压控制方法。该方法包括集中协同控制和就地自律控制两种模式,可根据配电网不同阶段的通信条件进行自适应选择和控制。本文从控制架构、原理和具体实现方法3个层面阐述了该方法对主动配电网过渡期电压控制的适应性和实用性,并以某实际线路为例,对传统电压控制方法和本文所提方法进行仿真对比,结果验证了所提方法的有效性,并表明该方法在节能降损、改善电压质量等方面具有优越性。

As for the situation of reactive power voltage control method of existing distribution network which neither achieves temporarily regional cooperative neither control nor satisfies the effect of traditional control method. In this paper,a kind of adaptive dual voltage control method of active distribution network is proposed based on the feature and need analysis of reactive power voltage of the distribution network in different development stages. This method includes such two modes as centralized cooperative control and local and local self-discipline control. And the self-adaption selection and control can be performed as per the communication condition in different stages of distribution network. In this paper,the self-adaption and practicability of the voltage control of the transition period of active distribution network is described from such three aspects as control frame, principle and specific achievement method. The traditional voltage control method and the proposed method in this paper is simulated and compared with certain actual line as an example. The effectiveness of the proposed method is verified by the result,showing that this method has superiority in the aspects of energy saving and loss reduction and improvement of voltage quality etc.
