Power System Studies

Millbrook Test Labs

SPE was contracted by Lark Power Services to undertake a wide range of power system studies for a new 7.5MW diesel generating plant in Derbyshire, for the new STOR / EFR response contracts.

SPE’s scope included a short circuit G74 study and protection coordination study using the ETAP software package. This required the creations of a detailed model of the whole power system, and a Time Current Curve plot generated for each of the main overcurrent and earth fault coordination scenarios.

SPE also carried out a detailed P28 transformer energisation study using the EMTP-ATP simulation package to determine the voltage disturbance caused by energising the transformers individually or as a group. This study also reviewed the long-term and short-term flicker created by the PV units on the

SPE was contracted by Red Engineering, on behalf of AVK to carry out a series of power system studies and preliminary design work to support a new battery test laboratory at Millbrook Proving Ground, in the UK.

SPEs scope was to develop a high level LV design and configuration.  This included the selection of cable sizes, switchgear ratings and earthing configuration to support development of an island power system, as the local grid did not have enough spare capacity and resilience.

Once the preliminary design had been completed, SPE then carried out some detailed power system studies to look at the behavior and response of the system.  This was assessed under a variety of different static and dynamic loadflow cases.  SPE also conducted a short circuit study and a harmonic study.
