摘要
本文引入状态空间表示连续型电能质量,构造代表设备对电能质量耐受能力的容许边界面,提出电磁兼容度、不兼容度指标来评估电能质量对电网中用电设备的影响。探讨电能质量状态空间表示在电能质量综合评估、电能质量运行状态相关性分析与电能质量预测和预警中的应用,给出分析过程。
A state space is introduced to express continuous power quality( PQ) in this paper. A tolerance boundary is designed to represent the PQ tolerance of equipment. Electromagnetic compatibility and incompatibility degree indices are proposed to reflect the influence of PQ on the equipment connected to electric power network. The PQ state space representation and its applications for PQ comprehensive assessment, operation status correlation analysis and forecasting and early-warning are explored respectively. The analysis processes are given.
