Abstract :
In the early days of power transmission problems like voltage deviation during load changes and power transfer limitation were observed due to reactive power requirements of the transmission system. Today these problems have even higher impact on reliable and secure power supply in the world of globalisation and privatisation of electrical systems and energy transfer. Fast and highly reliable power electronic devices (thyristor valves) in static VAr compensators (SVC) and HVDC applications proved their effectiveness in HV transmission systems to reduce energy transfer limitations. Influence of reactive power unbalances on the transmission systems and application of dynamic shunt compensation ie SVC is discussed. Detailed information about the used components in SVCs is provided
