Title of the Project :-CONTROL CHARGING OF CAPACITOR BANK

Project Summary

For improving the power factor, we use a large value Capacitor Bank inparallel to the load for a single phase or three phase power systems.Switching of these capacitor banks is made by using contactors or largecurrent carrying capacity relays. But switching one of the supplies causessudden charging of capacitor. This causes high peaks at the output ofcapacitor for short period. Due to this sudden surging there is loss of dielectricin the capacitor & life of capacitor reduces.

We control the switching operation of capacitor bank by using controlcircuit. So, life of capacitor bank will increase.

Technical details of the Projects

o Origin of the Proposal:-

While taking training in G.S.S. Bhinmal during 12 April to 12 May weobserve the following problem in switching capacitor bank. Whileswitching the capacitor banks there was degradation in their lifebecause of loss of dielectric in capacitor because of high surges.

We discuss this problem with site engineer and we can along for thissolution that if we can control the switching operation by using a circuit.

o Definition of the problem:-

In transmission lines for power factor improvement capacitor banksare used. While switching of those capacitor banks surges of high voltageare generated. Due to those high voltage surges , high dielectric loss takeplace in capacitor and sometimes it flashes the capacitor bank. It resultsthat reduce in life of capacitor banks.

o Objectives:-

1) Reducing the surge voltage while switching the capacitor banksusing control circuit2) Increasing in life of the capacitor connected in capacitor banks usingcontrol circuit.

o Work Plan:-

1) Design blue print of circuit2) Program creation for microprocessor used.3) Do the simulation of the circuit4) Create a hardware using components, CRO and bread board.5) Make it for 3phase.6) Increase the values of banks used.7) Will be tested on transmission lines 220 Volt load end.

o Time schedule:-

1) 1phase model within 3 months2) 3 phase model in next 7 months will be completed.

o Proposed outcome/ findings:-

Switching surges on the capacitor bank will reduce and hence longlife of capacitor banks.

o Details of facilities to be provided by the Institution:-

Function generator, Power System Lab for testing
