This project involved a comprehensive power system study to support expansion of an industrial power system up to 385 MW through addition of a new 220 kV cable feeder from the grid to the substation. The study covered critical analyses including load flow, short circuit levels, motor starting, transient stability, harmonic performance, voltage flicker, phase unbalance, voltage fluctuation and load cycling effects. Detailed system models were developed using DIgSILENT PowerFactory to assess electrical behaviour of the plant network, including evaluation of the impact of an SVC system used for electric arc furnace load compensation. Deliverables included the complete simulation model, system study reports and final recommendations to support reliable operation under steady state and dynamic conditions.

TCE's Scope

TCE acted as owner’s consultant and developed the detailed network simulation model in DIgSILENT PowerFactory. The scope included load flow analysis, short circuit evaluation, motor starting studies, transient stability assessment, harmonic studies and evaluation of voltage related performance parameters including flicker, unbalance, fluctuations and load cycling effects. The scope also included assessment of plant behaviour considering the SVC system used for compensation and delivery of the full model along with study reports and recommendations.

Impact

The assignment enabled structured validation of plant electrical performance for a 385 MW operating condition with a new 220 kV grid feeder. The delivered simulation model and study reports supported safer and more reliable operation by identifying performance behaviour across steady state and disturbance scenarios, and by providing recommendations that strengthen stability, power quality and operating efficiency of the expanded electrical system.
