Количество потребителей с нелинейной и несимметричной нагрузкой, ухудшающих качество потребления электроэнергии, постоянно
возрастает. Возрастает и число нагрузок с повышенными требованиями к качеству поставки электроэнергии. В этих усложненных условиях
потребления и поставки энергоснабжающие организации должны обеспечить каждого потребителя электроэнергией требуемого качества.
Рассмотрен единый подход к измерению и компенсации неактивных составляющих полной мощности в условиях учета величин каждой
неактивной составляющей отдельно в рамках разработки обобщенной теории мощности.
The number of consumers with nonlinear and unbalanced load, degrading the quality of electricity consumption is constantly increasing. Increases the number of loads with higher requirements to the quality of supply of electricity. These complicating conditions of consumption and supply the energy supplying organization must provide each consumer with electricity of the required quality. Under asymmetric voltage to the minimization of losses and the creation of a balanced power mode becomes multiobjective. Improvement of the methods of compensation under asymmetric voltage requires a further development of the theory of power. The creation of a methodology of measurement and assessment will require knowledge of the magnitudes of each inactive component separately, which leads to the development of a unified approach to the measurement and compensation inactive components of full power and the development of a generalized theory of power. Only a 3–wire system with symmetrical voltage eliminating pulsations and summarization of the conductivities of the phases is equivalent to problem (power surges and power asymmetry of the conductivities of the phases are equal). Under asymmetric voltage, the power is different, their analysis for electrical systems requires the creation of vector mathematical models of energy processes unsymmetrical modes 3–phase systems. Generalized mathematical model for both the 3–and 4–wire electrical systems defines the General approach to the development of the theory of power.
