To the theory of modeling of electric power and electric contact systems

Abstract This study evaluated questions of optimum control solution of ordinary differential equations’ nonlinear system which in particular, describes control processes of electric power systems. Conducted numerical experiments have shown sufficient efficiency of the implemented algorithms. It has been shown that essential feature of heating conditions in contact space occur in the moment of contact closure or contact breaking, which has t−1/2 order.

This study presents the algorithms for modeling of scheduled repairs of generating equipment when assessing the resource adequacy of electric power systems by the Monte Carlo method that relies on random events. We present an analysis of the algorithms adopted in the available software and computer systems used to assess the resource adequacy and highlight their shortcomings. We propose an algorithm for modeling of scheduled repairs of generating units that does away with the flaws of the algorithms adopted elsewhere. In the final part of the article, we present the findings of numerical experiments that test the performance of the algorithms.

In Indonesia, especially at PT PLN (Persero), SCADA has been known and started to be implemented in the control of electric power systems since the early 1980s in many other countries that are more advanced, SCADA application is growing in line with the development of computer technology and telecommunications. By the time the development is not as sophisticated SCADA now, there are thought to facilitate maneuvers on a system that is simple to use SCADA network we can supply additional power or power outage easily do so overloaded that did not happen. After implementing a SCADA system occurred saving time for 2906 minutes or 48.44 hours, and the frequency of outages 4 times less than that before implementing the SCADA system. This means that the reliability index SAIDI and SAIFI much better at the moment after the implementation of the SCADA system.
