Application of Power System State Estimation

Application of Power System State Estimation: Application of Power System State Estimation – In real-time environment the state estimator consists of different modules such as network topology processor, observability analysis, state estimation and bad data processing. The network topology processor is required for all power system analysis. A conventional network topology program uses circuit breaker […]

Treatment of Bad Data

Treatment of Bad Data: Treatment of Bad Data – The ability to detect and identify bad measurements is extremely valuable to a load dispatch centre. One or more of the data may be affected by malfunction­ing of either the measuring instruments or the data transmission system or,both. Transducers may have been wired incorrectly or the […]

External System Equivalencing

External System Equivalencing: External System Equivalencing – One of the widely practiced methods used for computational simplification is to divide the given system into three subsystems as shown in Fig. 14.4. One of these is referred to as the ‘internal’ subsystem and consists of those buses in which we are really interested. The second subsystem […]

Tracking State Estimation of Power Systems

Tracking State Estimation of Power Systems: Tracking State Estimation of Power Systems is important for real time monitoring of the system. As is well known, the voltages of all real system vary randomly with time and should therefore be considered to be stochastic processes. It is thus necessary to make use of the sequential estimation […]
