Using innovative electrical and electronic devices in the reduction of panel size

摘要

Good substation panel design must take into account many requirements. One important factor is panel size. TNMP has over the last years employed new storage media, state of the art relays and a reduced number of test interfaces to reduce overall front panel size by 60%. The harmonization of all these devices calls for an advanced testing and maintenance approach. The close interaction of panel design with maintenance and asset management is improving TNMP's operating procedures. While we are continually challenged by the rugged environment of our installations (part of TNMP's service area includes one of the largest refinery complexes in the country), our substations are at the forefront of automation. This paper intends to look at panel design from a fresh perspective. Based on the real-world experience of TNMP, panel space and installation costs savings will be discussed and quantified.
