Properties Analysis of Dual IPCs 240 with Three Branches Case Study in an Energy Transmission Line Connected to a Hydroelectric Mini-Power Plant

Abstract

In this paper, the newly developed “Dual Interphase Power Controller (IPC) 240” technology is used to increase the reliability of transmission lines for small renewable energy plants. This asymmetric compensation method based on symmetrical components has used two IPC. The first one is placed at the sending end of the line and the second IPC at the receiving end of the line. During normal operation of the transmission line formed, the electrical service continuity is ensured at the load using reactances, which adjust according to the power angle. When a permanent single-phase fault occurs, triggering the circuit breakers of the infected phase, the two IPCs are reconfigured so that the first performs a three-phase / two-phase transformation and the second a two-phase/three-phase transformation of voltage to continue providing a sufficient power for the load. Data from a power transmission line (30 kV-5 MW) from a mini hydroelectric power station has been used in a virtual network under Matlab/Simulink to test the functions dedicated to this technology. The results of the tests obtained and presented show the feasibility of this technology. The efficiency is also guaranteed because the electricity service is 100% assured in the absence of contingency and almost 70% during the contingency of the single-phase short-circuit type.
