摘要
在分析同步电动机功率因数原理的基础上,提出了以恒功率因数为控制目标提高电网功率因数的方案,设计了以恒功率因数为控制目标对励磁电流调节的同步电动机励磁装置,详细讨论了基于W77E85单片机的励磁控制系统的软、硬件设计。实验表明该方案可行有效。
On the basis of analysis of principle of power factor of synchronous motor, a scheme of improving power factor of power network was put forward which took aim at control of constant power factor. An excitation device of synchronous motor for regulating excitation current was designed. The software and hardware design of excitation control system based on W77E85 single-chip microcomputer was discussed in details. The experiment showed that the system is feasible and effective.
