电压暂降源的上下游定位有着明确供用电双方责任的作用。面对传统定位方法中负荷模型适用性差的难题,文中以戴维南等效模型为基础,通过比较电压暂降前后上游正序参数的变化,提出了一种电压暂降源定位方法。首先,对上游正序参数进行辨识,通过比较电压暂降前后上游系统正序参数的变化来确定电压暂降源的上下游位置。考虑参数不确定性、计算误差和测量误差的影响,提出了基于概率的改进判据。考虑误差对定位结果的影响,在定位模糊区域内引入概率型指标,定量分析了引起电压暂降上下游双方的责任,提高了定位结果的合理性。最后,通过IEEE标准模型验证了所提方法的正确性和有效性。
The upstream and downstream locating of the voltage sag source plays a role in clarifying the responsibilities of both the power supplier and the consumer. Facing the problem of poor applicability of the load model in the traditional location method
based on the Thevenin equivalent model
this paper proposes a voltage sag source location method by comparing the changes of the upstream positive sequence parameters before and after the voltage sag. Firstly
the upstream positive sequence parameters are identified
and the upstream and downstream positions of the voltage sag source are determined by comparing the changes of upstream system positive sequence parameters before and after the voltage sag. Considering the influence of parameter uncertainty
calculation error and measurement error
an improved criterion based on the probability is proposed. Considering the influence of errors on the location results
a probability index is introduced into the location fuzzy area
to quantitatively analyze the responsibilities of the upstream and downstream parties that cause the voltage sag
which improves the rationality of the location results. Finally
the correctness and effectiveness of the proposed method are verified by the IEEE standard model.
