Suppose these distribution systems consist of 3 load lane which is attached to the same distribution line. If due to some problem, load lane one is off but another load lane also connected to the same line so that these two load lanes also become off if there is no problem in these load. So that main part of our project is to “Relay co-ordination for electrical distribution system using PLC for stand by supply arrangement”. In these project when one load lane is off, the other load lane which is attached to the same line will be automatically on through relay. Key Words: programmable logic controller (PLC), Current transformer (CT), Relay, instrument transformer (IT), Rectifier etc. 1.INTRODUCTION PLC can help in achieving complete automation. In above years there are many techniques are done by our engineers with the help of relay synchronization. When PLC was not seen, control, sequencing, and safety interlock logic for manufacturing automobiles was accomplished using hundreds or thousands of relays, cam timers, and drum sequencers and dedicated closed-loop controllers. The process for updating such facilities for the yearly model changeover was very time receiving and expensive, as electricians needed to individually rewire each and every relay. The main purpose of this project is to rescue the distribution transformer in power system network against the internal and external faults. In the past the movements of industrial machines were controlled by relay cards. These relay-controlled systems were replaced by PLC. The primary function of the PLC was to perform the linear operations that were previously implemented with relays. Overloading of transformer beyond the rating transformer rise in temperature of both transformer oil and over current fault accrue in second side of distribution transformer. as the winding temperature increases it will increase the stress on the insulation and then insulation degrade and may fail power system external faults to transformer can increase or decrease voltage transformer which lead to over voltage. 1.1 WPL SOFT WPL Soft is a programming software that are made for the Delta DVP-PLC series used under WINDOWS. also for general program planning and other general functions (e.g. cut, paste, copy, multi-windows, etc.) Today, PLC is being used in every process and manufacturing industries, apart from knowing the wires and connections, anyone should know the way to do PLC programs. PLC Programmable logic controller is an industrial solid state computer that monitors input and output, and makes logic-based decisions for automated processes that’s make work easy. Delta PLC is a control system using electronic operation. It’s easy storing procedures, handy expanding principles, functions of sequential/position control, timed counting and input/output control are widely applied to the field of industrial automation control. WPLSoft is a program-editing (logic development) software made for the Delta DVP-PLC series used under WINDOWS. And this course is covering complete programming of PLC Model DVP-14SS2 of Delta PLC. After doing this course, you can softly program the other PLC. This software is also used for all the PLC series. And the instructions will be the same. This course will teach you step by step How to make a Ladder Logics and Programming to any industrial process Control. We have made explanation by Real Time LIVE Camera and Designing Software to understand the concepts clearly. 2.
