The Rate of Change Kinetic Energy (RACKE) method achieves considerable reduction in computing time by virtue of the way that it does not need the solution of system equation beyond fault clearing time. In RACKE method the machine which tends to lose synchronism can be defined as that which has the largest negation RACKE value. The injection of the brake ought to be achieved when RACKE of the machine liable to be unstable reaches its maximum negative value. Elimination happens when RACKE of the machine is zero and disturbance angular velocity passes through zero changing sign from positive to negative. To defining the instant of injection and elimination of brake, RACKE method can be used to investigate the transient stability margin of a power system through evaluation of RACKE value at the instant of fault clearance. The simulation demonstrates that the applying of a braking resistor at the terminal of each of the machines, pulling of synchronism, simultaneously brings the system into stable trajectory. It is clear from the results obtained that dynamic braking depending on the RACKE criterion for insertion and removal of the brake gives excellent results in an enhancement of transient stability margin.

“…The Braking Resistor (BR) can be viewed as a fast load injection to absorb excess transient energy of an area which arises due to severe system disturbances. A number of studies regarding braking resistors have been described in the literature [1][2][3][4][5]. But in all these switching strategies, fuzzy logic control schemes have not been used.…”

A Fuzzy Logic Controlled Braking Resistor Scheme for Transient Stability Enhancement

A large power system is often subjected to stability problem. This paper deals with the investigations regarding the transient stability enhancement of the electric power system making use of a fuzzy logic controlled braking resistor scheme. Following a fault, variable rotor speed of the generator is measured and the firing-angle of the thyristor switch in the braking resistor is determined from the crispy output of the fuzzy controller.
