From Power Quality to Power Experience

With development of information technology and high-tech companies, power requirements have turned from quantity to quality. Power quality issues are becoming more essential for power companies. Existing power quality standards are described by stable or transient states of current and voltage, from a perspective of power supply. In practice, it is up to customers' sensitivity and actual experiences for evaluation of power quality. In this work, power experience is proposed as a composite criterion of both existing power quality standard and related customers' information. From a perspective of customers' experience, the concept, features, and standards are proposed for power quality of experience. A case study from Shenzhen Power Supply Company is given, demonstrating that power quality of experience is more feasible in actual work for power quality evaluation.
