“…First rule in applying FCL is that limiting of distribution system's current is not used to eliminate failure and only limits current's amplitude so that circuit breaker with complete security and without additional overload cuts off. It is noteworthy that limiting of fault current should not destruct protecting system [16]. Installation locations of FCL in one large distribution substation [29].…”

Increased generation capacity along with entrance of new power plants to the grid has caused increase in the level of short circuit in transmission grid substations. In this paper, methods for decreasing fault current used theoretically and practically are gathered briefly first. Then, short circuit level is studied in transmission substations at Azerbaijan regional electricity company region in 2014 to introduce practical methods to decrease fault current. Short circuit level of mentioned transmission grid is analyzed using DIgSILENT and appropriate methods are proposed to decrease fault current.Index Terms--Short circuit level, fault current limiter, Azerbaijan electricity grid, DIgSILENT.

“…The method of application of DC equipment is equal to the enlargement is infinite. The study of short-circuit current limitation focus on loop unlock, transient current features of newly inserted elements(distributed system or power electronic equipments) [7][8][9]. Since the short-circuit problem is not so urgent in the traditional power system, the current limitation theory has been neglected for a long time.…”

It has become pretty common that more power supplies are growing to be located near load centers, as well as the closed loop operation, which have caught the problem of short-circuit current exceeding standard. Considering this issue has not got enough attention, the available current limiting methods in the ring power system with multi-sources have been studied and concluded as two means that are increasing circuit impedance and decreasing circuit numbers. Then the principle of the methods is investigated by analyzing the relationship of the changing rate between short-circuit current and the impedance matrix, branch impedance and so on. Furthermore, the current limitation procedure is proposed and applied to an actual ring distributed network with multi-sources, the simulation and practical operation results validate the effectiveness of the proposed methods and procedure Index Terms-multiple sources; loop closing; short-circuit current limitation; circuit impedance; circuit number I.

Limiting the short-circuit current is of great significance to keep the safe and steady running of the power system. A novel fault current limiter (FCL) is presented. A high speed switch is used to rapidly break the short-circuit current. A triggered vacuum switch (TVS) is used to discharge a precharged pulse capacitor so as to quench the arc in the high speed switch quickly and to realize the active transfer of the short-circuit current. A resistor is used as the current limiting component. The parameters of a FCL of 10 kV voltage level are designed. Simulations of the FCL in an oscillating circuit are performed by means of the ATP software. Experiments of a FCL sample device are also carried out in the oscillating circuit. The experimental results are in agreement with the simulation results. The current transfer characteristics and the current limiting effect are testified.Index Terms-Current transfer, fault current limiter, high speed switch, pulse capacitor, triggered vacuum switch.
