| Abstract | |
Rural electrification plays an important role in social and economic development for small regions and this still is a great challenge for electrical engineers. Small towns located close to high voltage transmission lines and have no electrical power supply due to high cost of conventional electrification projects. Solutions using capacitive coupling and isolated shield wire as electrical supply method are analyzed in this work aiming to energize a basic load considering rural populations of less than 1000 inhabitants. A premisse of isolated electric load of 500~kW was considered during the research. Simulations were performed in a 500 kV transmission line system based on actual data. Sections of 100 km isolated shield wires were used to attend the load, resulting in 30 kV induced voltage. The equivalent system has poor voltage regulation, being necessary to develop a specific regulation system based on resonant tuning circuit. Several different conection configuration of rural feeder were analyzed to maximizing power system output. Both steady state and transient state analysis were perfomed (AU) | |
