原油电脱水高频高压脉冲电源研究

Study of High-frequency and High-voltage Power Supply used in crude oil electric dehydration

目前油田原油含水率渐高,常规脱水方法已经不能满足。鉴于高压直流脉冲电脱水的种种优点以及高压脉冲电源研制难的现状,本文提出了一种基于脉冲同步叠加的方式产生高频高压脉冲的方法。文中详细介绍了脉冲同步叠加的原理,给出了高压脉冲形成电路结构,采用改进型PI控制器进行控制并建立了其系统框图。最后通过仿真分析,验证了电源实现的可行性。

The moisture content of crude oil in oilfield is larger,the methods of routine dehydration can not satisfies. For the advantages of high voltage pulse electric dehydration and difficulty of developing high voltage pulse power supply,this paper presents a measure which uses pulse adding synchronous to form high-frequency and high-vohagepulse.In this paper,it recommends the theory of pulse adding syn -chronous, gives the circuit structure of forming high-voltage pulse,adopts improved PI controller and found the block diagram of the controller. Finally it proves the feasibility of power supply through the simulation.
