PublicationThe magnetic flux density of various geometries of Rogowski Coil for overvoltage measurements( 2020-01-01)Overvoltage phenomenon is the common problem that always occurs in the power system and can cause the electrical system network breakdown, and in some cases, it may explode. The frequent overvoltage also can affect and degrade the lifespan of the electrical power system components and network. Thus, the overvoltage sensor is needed to overcome this problem matter. The Rogowski coil (RC) is one of an inductive coil group, and it is suitable for measuring the alternating current (AC) and transient currents or overvoltage. This paper demonstrated the effect of RC magnetic flux density, B with difference cross-section, geometries sizing and the number of turns by using Finite Element Method (FEM). Commonly, there are three types of RC widely used; rectangular, circular and oval. Each of these cross-sections has different characteristics in term of performance. The results have shown that the rectangular cross-section is better than oval and circular cross-section based on the number of magnetic flux density.

PublicationGrid connected microgrid with power offset synchronization using c2000 processor( 2020-01-01)Droop based technique are common in inverter based microgrid implementation since no communication lines are required. However, the technique gives poor and non-flexible PQ power sharing performances. The proposed microgrid structure implements a microgrid central controller which communicates with the inverters using a low bandwidth communication to provide PQ power references. This paper presents the implementation of the proposed microgrid control, communication and synchronization using c2000 processor in Matlab Simulink.
