Kulik B. Principles of reactive power compensation in the existing electrical systems

This thesis is intended to solve the scientific challenge for developing the principles of reactive power compensation in power systems in order to improve their reliability and efficiency of their operation. The analysis of existing principles for assessing of the steady state regimes in designed power systems is conducted. It shows that the existing principles can not be applied for compensation of reactive power in operating electrical systems. Proposed and justified are evaluations of reactive power loads, which are designed to compensate reactive power in operating electrical systems. It is shown that statistical dependencies between the output and dependent parameters in steady state regimes should be used to predict the target modes of operation in operating electrical systems with artificial compensation. Developed in the thesis are the principles of reactive power compensation, which take into account statistical relationships between the output and dependent parameters steady state operating of electrical systems, design and operational characteristics of electrical systems and means of artificial reactive power compensation. Recommended are the algorithms for controlling the artificial compensation to improve the reliability of existing electrical systems, reducing costs of active energy for transportation, ensure an adequate level of power quality and the possibility of their technical implementation.
