摘　　要：定制电力(曾称定质电力、用户电力、用户特定电力)的概念是将电力电子装置用于1～35kV的配电系统,为向电能质量敏感的用户提供达到用户特需的可靠性水平和电能质量水平的电力。这些定制电力设备采用先进的电力电子器件和计算机的测控技术。定制电力技术的发展与许多电气设备对电能质量的敏感性密切相关,诸如某些数控生产线、变频调速设备、数据处理中心、集成电路生产车间、医院等。用户需要解决的电能质量问题,包括电压跌落、电压中断、电压闪变、谐波造成的电压波形畸变及电压调节问题。对配电系统电能质量问题的研究分析表明,电压跌落、瞬时断电占所有电能质量事件的50%以上。前述对电能质量敏感的设备,主要是受电压跌落、暂时断电而影响正常运行。因此,除无功补偿和解决谐波问题之外,定制电力的发展主要是解决电压跌落、瞬时断电问题。Custom power is the concept, it is the employment of power electronic equipments in medium voltage (from 1 kV to 35 kV) distribution system for the purpose of supplying a level of power quality that is needed by customer that are sensitive to power quality variation. Custom power equipments could improve to a level of reliability and power quality for customer based on modern power electronic devices and measuring and monitoring technology of computer. The development of custom power is relatively with sensitive grade of most electric equipments to power quality variation. For example produce line of some digital control, transducer, data management center, produce workshop of integrate circuit, hospital and so on. Custom power technology in general includes all equipment solutions used to correct the problems faced by end-user loads in response to voltage sags, voltage interruption, voltage flicker, harmonic distortion, and voltage regulation problems. Voltage sags and voltage interruption is the most power quality problem (exceed 50%) by analysis and research of power quality in distribution system. The sensitive electric equipments to power quality are manly effected from voltage sag and voltage interruption. Therefore, custom power will mostly give a solution for voltage sag and voltage interruption except for reactive power compensation and harmonic eliminating.
