Busbar Protection Scheme Based on Alienation Coefficients for Current Signals

Reactive Power Control Scheme Based On Correlation Coefficients for Voltage and Current Signals

.Abstract: In modern digital protection and control systems, a correlation technique has recently become the workhorse of quantitative research and analysis. In this paper, a correlation technique is developed for calculation of original power factor on-line, active and compensation reactive powers and determination of the required number of capacitor banks to get the desired power factor. Cros...

Protection scheme for transmission lines based on correlation coefficients

In modern digital power system protection systems, statistical coefficients technique is recently used for fault analysis. A correlation technique is developed for faults detection and discrimination. The proposed technique is able to accurately identify the condition of phase(s) involved in all ten types of shunt faults that may occur in extra high-voltage transmission lines under different fa...

A Novel Flux-Based Protection Scheme for Power Transformers

Internal Turn-Turn faults (TTF) are the most common failures in power transformers, which could seriously reduce their life expectancy. Although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as TTFs andshort circuit near the neutral point) cannot be detected by such schemes. Likewise, these rela...
