The paper considers an issue of large power systems optimal control. The analysis of basic control system concepts for normal and emergency operation conditions is performed. A general structure and organization of distributed control system operation of the large power system are presented (the control system provides automated coordination of actions from local control centers for power system operation). The task of distributed control system practical implementation is set up. It will give an opportunity to ensure global optimality of power system modes while providing a minimum level of power system vulnerability.

Cable Lines

Mikhail Dmitriev, St. Petersburg Polytechnical University

 

In recent years in our country on several different substations were recorded power transformer insulation damages. They occurred while switching of cable lines with XLPE insulation that is attached to windings of 6–35 kV. The article discusses the possible causes of accidents. In particular, attention is drawn to the fact that the cable lengths was not less a few kilometers, and often the line had multiple cables per each phase, i.e. in all cases it was about the connection of considerable capacity.

Abstract.

The paper considers some problems of functional coordination between relay protection systems and current transformers. Nonselective actions of relay protection devices when saturation of current transformers are analyzed. The application of new current converters is also considered and methods of relay protection devices adaptation to operate current transformers are proposed.

Keywords

: relay protection, core saturation, residual magnetic induction, error compensation
