COMPLEX APPLICATION FOR PROTECTIONS, CONTROL AND METERING CIRCUITS FOR 20 kV OVER HEAD LINE FEEDER, USING A DEVELOPMENT MICROSYSTEM WITH PIC 18F8722 MICROCONTROLLER

Ph. D. candidate Cirdei Cornel Dinu
Abstract:
The Application for Protection, Control and Meterring Circuits using a Development Microsystem, simulates protection, alarms, control and metering instruments, for 20 kV Over Head Line Feeder. The first function of present application makes a combination between coordinated and integrated systems, combining the safety of first with the fast operating of second and simulates protection operations, for the feeder described above. The second function of this application, is to command and supervise local and remote operations of Bus Bar Switches, Circuit Breaker and Earthing Switch, assuring the safety operation of each one, because of the interloks which are introduces for each specifical operation. Finally, the third function, is to analyse power quality indicators, as an digital measurement device, and being able to present selected details into four screens which are shown on the graphical display. The original contribution of this one is to count voltage, current and voltage fluctuations, out of Power Quality rules and to send alarm to the Substation Control Room.
