The aim of this paper is, firstly, to recall the basic concepts of SCADA (Supervisory Control and Data Acquisition) systems, and how Scada plays an important role in the field of power system. for the study of electrical power distribution system we need general set-up of automated power distribution laboratory in which we need the set-up of one generator panel, one transmission line panel, one receiving end panel and one Simatic s7 300 PLC System. a versatile distribution system simulator is developed which replicates the behavior of a distribution network as viewed from a computer based control centre. Keywords: Simatic s7 300 PLC System, SCADA and electrical power distribution system…show more content…
SCADA receive the signal from PLC output. if some part in the power system are unhealthy the SCADA gives signal to PLC for recovery of damage. 3. STUDY OF PANEL/EQUIPMENT 3.1 Grid Source Panel 440 VOLT 3phase input is to be connected on connector provided on left side of unit.HRC fuse is provided in each phase at input. Four pole MCB is provided on panel to isolate the system from mains Source A and Source B are two three phase 440V/5Amp supplies acting as Generator. IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 __________________________________________________________________________________________ Volume: 03 Issue: 04 | Apr-2014, Available @ 2 Grid source panel displays Voltage Vry, Vyb and Vbr and three phase current Ir, Iy and Ib on respective meters for both source A and source B. Also for source A sending end power factor is displayed on power factor meter. voltage selector switch is to be used to display Vry,Vyb and Vbr voltage. Power line Sensors: For source A voltage sensors for Vry, Vyb and Vbr, three current sensors for Ir,Iy and Ib and one 3P/3E/4W-trms power factor sensor is provided on sending end. also for source B three current sensors is provided on sending end. 3.2 Busbar with Simulated Transmission Line Two parallel Bus Bar A and B with 5A rating. Each BusBar is having three sections. BUSBAR WITH SIMULATED
