Abstract:
For economic operation of electric power system, load and transmission conpensation play a very important rule. These are also important for power system transisent stability. This project concerns with the power factor correction and voltage regulation at the receiving eng, which ultimately conpensate the whole system. If the load power factor is close to unity, the equipmentsupplying the load will be able to supply almost the same amount of poer as their KVA capacity of low power factor, the KVA ratings of the line and the equipment supplying the load should be high for the same power transmission. The Excess current for low power factor causes loss and voltage derop in the line and the wire needed for transmission and distribution should be larger in diameter to conduct more current. Conventional VAR compensators consiting of seitched shunt capactor/reactor banks have some limitations and have been replaced by new methods employing solid state devices which use thyristor controlled reactor and thyristor switched capacitor. the thyristor is usedas controlling elements and the reactice power is provided by large storage elements such as capacitor/reactor banks. These can be replaced by solid state PWM converters with minimum energy storage elements. This thesis proposes a novel approach using solid state PWM voltage source inverter where reactive power is provided by means of circulating current within the inverter. This system works by controlling the magnitude and direction of the fundamental component of the ac output voltage of the inverter. Compensation for reactive power can be achieved from full leading to full lagging with quick response time. This compensation system reduces the cost and space greatly. The proposed system designed, si simulated by PSpice electrical circuit simulator package using a new type of modelling feature called converter system model utilizing analogue behavioural modelling option on an IBM personal computer.
