Abstract

An analysis of the starting performance of tuned delta-modulated inverter-fed submersible motors is presented. Submersible motors are induction motors that have unique constructional features. These motors are required to operate in one of the most harsh environmental conditions. The operating characteristics of a submersible motor pump system require soft starting facility and variable-speed operation. To satisfy both requirements, a delta-modulated inverter supply is proposed, and the system starting performance is presented. The soft starting characteristic of the motor is obtained by the inherent V/F control of the delta-modulated inverter. The analysis is carried out using time domain representation of inverter voltages and the d-q axis model of the motor. The time-domain representation of inverter voltages is done using gate functions. The starting performances of submersible motors improved substantially. Though the analysis and results presented in this paper are for a submersible motor, they are equally applicable for any type of polyphase induction motor.<>

三角调制变频调速潜水电机的起动性能

分析了调谐三角调制变频调速潜水电机的起动性能。潜水电机是一种具有独特结构特点的感应电机。这些电机需要在最恶劣的环境条件下运行。潜水泵系统的运行特性要求具有软启动装置和变速运行。为了满足这两种要求，提出了一种增量调制逆变电源，并给出了系统的启动性能。电动机的软起动特性是通过增量调制逆变器的固有V/F控制来实现的。利用逆变器电压的时域表示和电机的d-q轴模型进行分析。逆变器电压的时域表示是用门函数来完成的。潜水电机的起动性能有了较大的提高。虽然本文的分析和结果是针对潜水电机的，但它们同样适用于任何类型的多相感应电机
