Modelling and simulation of transmission lines in a biological neuron

Transmission lines are an important part of a power system. Transmission lines have high power transmission capacity and they are prone to faults of larger magnitudes. Various faults occur in transmission lines. Therefore, protection relays are necessary to protect transmission lines. The purpose of protection system is to interrupt the faulty section from the healthy section because the fault currents may damage the electrical equipments. One of the protection relays is distance relay and it is mainly used in transmission line. Sometimes these relay are used for backup protection. Distance relays for determining the impedance need the voltage and current. Transmission lines are typically protected by distance protection relay. Distance relays are considered of high speed class and can provide transmission lines. Nowadays, numerical distance relays have been used instead of using electromechanical and static distance relays. The proposed model was verified under different tests such as single line to ground (L-G) fault, double line to ground (L-L-G) fault, line to line (L-L) fault and three phase (L-L-L) fault. SimPower System was used for modelling and simulation of distance relay, transmission lines and faults. The simulation results were obtained from MATLAB software shows the feasibility of analysis of transmission line protection with mho type distance relay for single line to ground fault, double line to ground fault, line to line fault and three phase fault at different location of transmission lines. The difficulties understanding on operation of distance relay can be cleared by using MATLAB/SIMULINK software.

This research paper focuses on modelling and simulation of 330 KV, 600 MW Shiroro Substation in the DIgSILENT Environment for the integration of Hybrid Solar PV – Hydro System to improve power supply in the Federal Capital Territory (FCT) of Abuja, Nigeria. A hybrid energy system is a system that combines multiple types of energy generations to satisfy the demand of the users effectively and efficiently. The Solar Photovoltaic (PV)/Hydro hybrid system consists of electrical energy generated from solar PV and hydro energy. Effect of environmental issues, reduction of fossil fuels in addition to its high cost have actively encouraged interest in great integration of renewable energy sources in power systems. This work capitalized on the possibilities of harnessing commercial solar energy and feeding it to the National grid through a nearby 330 KV substation at Shiroro Dam. The simulation is carried out in DIgSILENT (Power factory) environment. The Shiroro 16 kV, 330 kV, 600 MW Transmission Lines are modelled, and results of simulations of the five bus bars (Jebba, Shiroro, Gwagwalada, Katampe and Kaduna) voltages directly connected to Shiroro Network are: 331.8kV, 331.7 kV, 329.3 kV, 325.6 kV and 332.2 kV, respectively. All the values are within the Operational and Statutory Limits of the National Grid Code.
