摘　　要：火力发电厂中大功率高压电机消耗功率是发电厂用电的重要组成部分。随着机组调峰的频繁,高压厂用电动机的负载也频繁发生变化。在满足系统工艺要求的前提下,通过变频调整电动机的转速,可以满足节能的需要。The consumed power of high-voltage motors is an important part of electricity utilization in coal-fired power plant. With frequent peak regulation, The electromotor load in highvoltage house has also changed frequently. Under the condition of satisfying demands of process system, adjusting the rotation rate of electromotor through frequency conversion can satisfy energy-saving demand.
