摘要

通过介绍高压变频器在700MW机组的凝结水泵节能改造应用情况及变频改造方案的具体实施。对变频改造前后凝泵的能耗进行分析比较

充分说明高压变频器具有显著的节电效果。基本消除了阀门的节流损失

减少凝泵电机启动电流对系统和电机的冲击

保证了系统随时维持在最佳运行工况。对改造过程中遇到的一些问题进行了论述

主要是元件的散热不良易导致设备出故障

提出防止类似问题重复出现的对策

为同类电厂改造提供了参考。

Abstract

This paper introduces application of high-voltage conversion in 700MW units condensate pump. Compared energy consumption with before

it shows that high voltage converter has notable saving electric energy effect which basically eliminating the throttle loss of valve and ensuring that the system maintain the optimum operating conditions at any time.The problems during the process of frequency conversion transformation were discussed. The bad heat elimination often leads to equipment failure. The paper provided some measures to prevent similar problems from recurring response which can be reference of the same kind problem in other power plants.
