应用微机的功率因数临界补偿控制

A Critical Compensating Control of Power Factor by use of Microprocessor

本文从理论上给出在无功补偿中出现的临界投切的严格定义，首次提出一种临界补偿控制新算法，介绍了一种简单实用的相位检测方法，由此而构成的微机无功补偿器具有优良的特性。

In this paper, the critical switch on-off in reactive power compensating control is strictly defined in theory, a novel critical compensating control algorithm is first presented, a simple and practical phase measurement method is discribed. By this algorithm and method, a reactive power compensating controller besed-on microprocessor has excellent performance.
