This paper presents an improved local search method using bee colony optimization (ILS-BCO) to solve an economic dispatch (ED) problem with smooth cost function characteristic. The proposed ILS-BCO algorithm is an integration of lambda iteration and bee colony optimization (CLI-BCO) combined with golden section search and bee colony optimization (CGS-BCO). To show its effectiveness, the ILS-BCO was...
In case of safety instrument system as one out of one voting (1001) for fail-safe operation in motor drive system, this average probability of failure on demand may be inadequate for certain types desired security levels are higher. This paper proposes the design and analysis of 2003 voting sensor in electrical power drive system. This model is designed under safety specification of safety function...
This paper presents the technique for selecting the parameters based on PWM buck AC chopper. This results the optimal capacitor filter that produces the phase angle of input current in phase with that of input voltage. Therefore, the converter operates at unity input power factor. The simulation results by Pspice program are used to verify the proposed technique.
