Abstract

Consideration is given to methods for the parallel operation of frequency converters by applying the active load division. The simulation model of the converter is presented. It consists of three parallel independent modules. A new principle of constructing individual modules of a frequency converter and the principle of their communication interface exhibiting resistance to destabilizing effects and allowing safe operation under nominal conditions even with a 5- to 10% range in time and amplitude values of pilot signals are developed.

变频器并联运行方法分析

摘要

通过应用有源负载分配，考虑了用于变频器并行运行的方法。给出了转换器的仿真模型。它由三个并行的独立模块组成。开发了一种新的构造变频器单个模块的原理，以及它们的通信接口原理，该原理显示出抗不稳定作用的能力，即使在5至10％的导频信号的时间和幅度值范围内也可以在标称条件下安全运行。
