Small Signal Fault Analysis for Renewable Energy (Wind) Power System Distributed Generation by Using MATLAB Software (Simulink)

Abstract

In distribution system, wind power plants are becoming popular renewable energy sources. It employs Doubly Fed Induction Generator (DFIG) to generate power constructed on wind conversion. Short and long transmission lines, presence of faults and presence of Static Synchronous Compensator (STATCOM) are highlighted issues in this paper. Basically, this research develops investigations on some electrical variables such as voltage and current to control them. Distribution Static Synchronous Compensator (DSTATCOM) is proposed in this paper. Wind farm acts as a source while DSTATCOM is associated with the distribution system with a DFIG based wind farm. The controller proposed is DSTATCOM is modeled and simulated in MATLAB/SIMULINK and the results are given. A microgrid based small signal analysis is performed in the laboratory using MATLAB and different comparisons are made and simulation case studies are presented and validated.

GSM Based Smart Energy Meter System

“…In our project we have used current and voltage transformers and simultaneously as contradict to voltage detectors. A observation from the software organization is gained from the automatic energy meter which is a programmable one and the activities done by the meter is highly matched with the given enumeration a main advantage of automatic Energy meter is that we can disconnect and reconnect the power supply of the user without the help of the man power [14][15]. We can also reconnect the power supply once it is disconnected.…”
