A measuring method using the symmetrical components of three phase power systems as well as a measuring system model and obtained results have been presented. (Calculation of asymmetrical power in a three-phase system depending on symmetrical components). 展开 年份: 2011 ...
The paper presents a method for calculation of power of multiphase circuit. Using the vector and tensor notation for voltages and currents on circuit terminals the changes of instantaneous power have been described as third rank matrix. Decomposition of this power matrix into a symmetric matrix and...
2. How is the active power calculated in a three-phase system? The active power in a three-phase system can be calculated by multiplying the line voltage (V) by the line current (I) by the power factor (PF) and by the square root of three (√3), as shown in the formula: P =...
