Multivariable Hybrid Control System of the Distribution System Power Factor

摘要: Existing mathematical models of electric distribution systems containing a group synchronous motors considered as reactive power control object do not take into account the influence on each other through common source, which negatively affects only errors but also possible overload individual motors. In this paper, multivariable plant model an industrial system with two and field windings DC source was derived coefficient feedback proposed. The provides separate channels excitation current loop interacting in torque angle variables for group. parameters regulator are selected taking interaction channels, reduces value stability margin by 25–30%. case when supplied controlled is enough additional channel that activates capacitor bank, helps to maintain within normative limits. has been verified using MATLAB/Simulink simulation partially validated test oil cluster pumping station Barinovskaya, JSC Samaraneftegaz. proposed factor can be effectively used operating significantly variable consumption mode incorporating high drive.
