摘要

随着能源独立村计划的启动，印度尼西亚目前正在增加微型水力发电的使用，该计划在几个地区继续发展。本研究将AC-DC-AC变换器的设计与分析应用于与50kw微型水电厂并联的异步/感应发电机。AC-DC-AC转换器由发电机侧转换器(GSC)和负载侧转换器(LSC)组成，它们通过DC-Link网络背靠背安装。通过PSCAD程序的仿真，对控制器设计的有效性和动态特性进行了评价和分析。仿真分析分为2种故障场景，即:(1)负荷变化和发电机转差形式的小扰动分析，(2)输电网短路引起的大扰动分析。结果表明，该控制系统能够在负荷变化和永久性干扰的情况下稳定和调节功率流。

The AC-DC-AC Converter Design for Parallel Asynchronous Generator Based Microhydro Power Plants

The use of micro hydro energy for electricity generation in Indonesia is currently increasing along with the launch of the energy independence village program which continues to grow in several regions. In this study, the design and analysis of AC-DC-AC converter is applied to asynchronous/induction generators connected in parallel with 50-kW Micro Hydro Power Plant. The AC-DC-AC converter consists of a Generator Side Converter (GSC) and a Load Side Converter (LSC) which are installed back to back via the DC-Link network. The effectiveness and dynamic characteristics of the controller design were evaluated and analyzed through simulation using the PSCAD program. Simulation analysis is divided into 2 fault scenarios, namely: (1) Analysis of small disturbances in the form of changes in load and generator rotation differences, and (2) Analysis of large disturbances due to short circuits in the transmission network. The results show that the control system is able to stabilize and regulate the flow of power against changes in load and permanent disturbances.
