Objectives Develop guidelines for reactor switching transient recovery voltage (TRV) simulations at 33kV (and other voltages )Make recommendations for circuit breaker rating and mitigation options for inclusion in a company policy document. If the outcomes are useful, there could be the possibility of extending the project to cover higher voltages and series reactors. This project will be deemed successful if a more economical solution is determined for reactor switching.
Abstract Scottish Power Energy Networks (SPEN) propose to undertake an innovative research project to investigate whether standard switchgear can be used to switch shunt reactors, or whether specialised switchgear or switchgear of a higher rating is required. If it is found that higher rated switchgear is necessary, it will be determined if a more economical solution would be to modify standard switchgear by means of shunt capacitors, surge arrestors or snubber circuits. The similar technical principle will be similar between distribution (33kV or 11kV) as the transmission connected shunt reactor (at 132kV). The work for this study will be broken down into a set of discrete tasks divided into two study phases as listed below. Phase 1 Literature survey into shunt reactor switching Liaise with manufacturers and SPT Asset Management to define factory test data currently available Investigate current SPEN systems, simulate various items of equipment, designs and connections Investigate practical mitigation techniques Phase 2 Measure shunt reactor characteristics Practical testing of a vacuum circuit breaker and reactor combinationNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
