无功补偿综合实践平台的设计

The Design of a Comprehensive Practice Platform for Reactive Compensation

无功补偿是电气工程及其自动化专业学生所必需掌握的知识点之一。本文介绍了一种无功动态补偿综合实践平台的实现方案,利用调压器、异步电动机、同步发电机及灯箱模拟可变的有功及无功负荷,通过90度接线方式利用一表法测量系统的无功需求量。该值的变化决定投入分组电容的组别,实现了无功功率的测量—无功补偿的基本原理和实现—无功补偿效果评价的综合实践体系。实践证明,学生可以将多门课程中的知识点融会贯通成知识面,加深理解的同时增强了分析问题和解决问题的能力,效果良好。

Reactive compensation is one of the important knowledge points to the electric professional students. This paper introduces a design of the comprehensive practice platform as for dynamic reactive compensation technology. In this system, the simulative load is composed of a booster, an electromotor, a generator and an electric light group,and the reactive power is measured by one meter method, which decidesthe capacitance part that would be pluged in. So this system combines the ractive measurment,the compensation principle and the evaluation method to form an interrelated parts. The fact proves that students summarize all the relactive knowledge points, and the ability of analysis and resolving problems is trained to a certain extent.
