摘要

为解决电动给水泵(电泵)工频与变频并列控制问题

本文通过现场采集数据和数据分析

得出电泵勺管指令与电泵转速、电泵变频器指令与电泵转速的函数关系;同时

根据泵与风机的比例定律

得出电泵勺管指令与电泵变频器指令之间的函数关系

依据该函数关系设计出一种工频泵与变频泵并列调节的新型控制方式

并在实际工程中得到了成功应用。该方案对相同配置电厂的电泵变频改造有借鉴作用。

Abstract

In order to solve control problems in AC-motor feed water pump and variable-frequency feed water pump parallel operation

this paper proposed a new control scheme.Through on-site data collection and data analysis

the functional relationship between pump scoop control instruction and pump speed was respectively obtained.Moreover

according to the proportion law of pumps and fans

the functional relationship between the pump scoop control instruction and variable-frequency control instruction was obtained.On the basis of this function relationship

a new control scheme was designed and had been applied in practical engineering successfully.The scheme this paper put forward may serve as a reference for designing the control strategy in similar retrofit of the electrical feed water pumps.
