Types of Facts Controllers in Power System

Types of Facts Controllers in Power System: The development of FACTS controllers has followed two different approaches. The first approach employs reactive impedances or a tap changing transformer with thyristor switches as controlled elements, the second approach employs self-commutated static converters as controlled voltage sources. In general, Various types of facts controllers in power system […]

Difference Between SVC and Statcom

Difference Between SVC and Statcom: Difference Between SVC and Statcom may be noted that in the normal linear operating range of the V-I characteristic and functional compensation capability of the STATCOM and the SVC are similar. However, the basic operating principles of the STATCOM, which, with a converter based var generator, functions as a shunt-connected

Line Compensation in Power System

Line Compensation in Power System: Line Compensation – Ideal voltage profile for a transmission line is flat, which can only be achieved by loading the line with its surge impedance loading while this may not be achievable, the characteristics of the line can be modified by line compensators so that Ferranti effect is minimized Under

Load Compensation in Power System

Load Compensation in Power System: Load compensation is the management of reactive power to improve power quality i.e. V profile and pf. Here the reactive power flow is controlled by installing shunt compensating devices (capacitors/reactors) at the load end bringing about proper balance between generated and consumed reactive power. This is most effective in improving

Limitations for Loading Capability of Transmission System

Limitations for Loading Capability of Transmission System: There are three kinds of limitations for loading capability of transmission system: Thermal Dielectric Stability Thermal capability of an overhead line is a function of the ambient temperature, wind conditions, conditions of the conductor, and ground clearance. There is a possibility of converting a single-circuit to a double-circuit
