The article deals with the linear pursuit problem with n pursuers and m evaders with equal opportunities for all participants and geometric restrictions on the control of players. The evaders use program strategies, and each pursuer catches no more than one evader. The goal of the pursuers is to catch a given number of evaders, and each evader needs to be caught no less than a certain number of pursuers...
Power transmission lines of low voltage are rarely damaged by direct lightning strikes, because they are short in length and are protected by high objects which surround them. However, the induced voltage generated by lightning indirect strikes, can cause significant damage to the power equipment and for the control or protection circuits. The paper presents the results of computer simulation the...
The article presents the results of researches of transients in 35 kV vacuum circuit breakers when interrupting load currents in particular schemes. It is shown that in some cases disconnection of load can lead to reignition in vacuum circuit breakers, followed by overvoltages, which can be dangerous for the circuit breaker and other power equipment. Moreover, transient behavior can affect the amplitude...
This paper presents the efficiency of the phase-shifting transformer (PST) installation in the power supply system of Saint-Petersburg and the Leningrad region which allows to maintain power flows within the defined range and to limit short-circuit currents to the values which do not exceed the breaking capacity of switching devices. After the analysis of various PST operation conditions, its optimum...
