Voltage Stability Improvement using STATCOM and SVC
Voltage stability of a system is affected by reactive power limit of the system. FACTs devices improve the reactive power flow in system thereby improving voltage stability. This paper explores the effect of SVC and STATCOM on static voltage stability. IEEE14 bus system has been used to demonstrate the ability of SVC and STATCOM in improving the voltage stability margin. These FACTs controllers...
متن کاملVoltage Stability Improvement in Power System by Using Statcom
Voltage stability problems usually occur in heavily loaded systems. Nowadays the power demand increases enormously, hence in a large interconnected power system network subject to stress conditions. This situation can be handled by increasing the generation or reducing the transmission losses. When the load increases suddenly, voltage magnitude also varies beyond the permissible voltage stabili...
متن کاملCoordination between SC and SVC for Voltage Stability Improvement
At any point of time, a power system operating condition should be stable, meeting various operational criteria and it should also be secure in the event of any credible contingency. Present day power systems are being operated closer to their stability limits due to economic and environmental constraints. Maintaining a stable and secure operation of a power system is therefore a very important...
متن کاملTransient Stability Improvement Using UPFC and SVC
With increased power transfer, transient stability is increasingly important for secure operation. Transient stability evaluation of large scale power systems is an extremely intricate and highly non-linear problem. An important function of transient evaluation is to appraise the capability of the power system to withstand serious contingency in time, so that some emergencies or preventive cont...
متن کاملComparison of SVC and STATCOM in Static Voltage Stability Margin Enhancement
One of the major causes of voltage instability is the reactive power limit of the system. Improving the system's reactive power handling capacity via Flexible AC transmission System (FACTS) devices is a remedy for prevention of voltage instability and hence voltage collapse. In this paper, the effects of SVC and STATCOM in Static Voltage Stability Margin Enhancement will be studied. AC and DC r...
