新型的转差频率励磁发电机

本文介绍最近研制的一种新型变速恒频稳压风力发电机——转差率励磁发电机。这种发电机系统结构简单、制造容易、成本低廉。不但适合于变速风力发电系统,而且适合一切随机性很强的能源,如太阳能、潮汐发电系统等。文中叙述了发电机系统的优点和恒频稳压原理;研究了发电机运行分析方法;讨论了发电机派生设计和与电源配合问题;分析了发电机在超同步和亚同步发电时的能量流传;给出了稳态运行时主要特性曲线。对恒频稳压控制电路特点也作了介绍。

A New Type Generator with Slip Frequency Excitation

This paper introduces a new type wind turbine generator recently developed with variable speed,constant frequency and constant voltage generator system are the simple in the constru ction,easy in making and cheap in cost.It can be used not only by vari- able speed wind turbine generator system but also by all random energy sources such as solar energy,morning and evening tides generator system etc. The paper expounds the advantages of the generator system and the principle of constant frequency and constant voltage.It investigates analytical method of the ge- nerator operation,discusses the derive design of the generator and how to match with source of power.It analyses the energy flow under the above and below synchronous speed operation of the generator and gives the main steady state operating characteri- stics.It also introduces special advantage of control circuitry which keeps constant frequency and constant voltage of the generator system.
