Compensation objectives and Currents' Physical Components-based generation of reference signals for shunt switching compensator control

Document Type


Publication Date



Compensation objectives in three-phase asymmetrical systems with non-sinusoidal voltages and currents, from the perspective of the loading and/or supply quality improvement, are discussed and classified. Fundamentals of generation of the reference signal for shunt switching compensator (SSC) control with the Currents' Physical Components (CPC) power theory are also presented. The CPC enables to fit the control algorithms to various objectives of Compensation and to the load properties. This is because the CPC power theory, being founded on power phenomena in electrical systems, provides clear insight into power properties of electrical loads. In spite of the fact that the CPC power theory represents a frequency-domain approach to the identification of the power properties, the CPC-based algorithms are not very computationally demanding and make a quasi-instantaneous control of switching compensators possible. © The Institution of Engineering and Technology.
