The modern methods for designing of medium voltage switchboards technology of power plant´s refineries

Any refinery needs an independent power plant which is most important for running all of the processing units under steady state conditions [1]. We are still considering the constructions of medium voltage switch gears (MVSWGR´s) in the conventional way although the vacuum theory has proved. Digital relays with their automation are offering good facilities for sending on the power of medium voltage distribution systems. But, it is still needed for these innovations to be more qualified. This research paper deals with the involvement of a binary function for receiving 11KV either from the extra high voltage National Grid distribution network of 220 kV which is called the modified IEEE 21 bus-test-case or sending the floating power generation from the refinery to the grid which is called the modified IEEE 23 bus-test-case and is based on the MATLAB/MATPOWER testing system [2], [3]. Moreover the designing of circuit breaker shall be further tested using existing parameters of the MATLAB switching system. This paper explains many recommendations and conclusions.
