2022

Technical assistance related to high armour currents and phase current unbalance in a medium voltage cable circuits with 1 single core cable per phase and 3 single core cables per phase. Confidential client.

Assessment of options for reuse of two intact cores of a damaged three core submarine cable. Confidential client.

2021

Circulating and armour currents in LV installation – Confidential client. Provision of technical assistance to identify the reasons for high phase current unbalance and armour currents with five quad groups of conductors (L1/L2/L3/N) operating in parallel on a shared cable ladder. Identification of reasons for observed currents and excessive cable heating and verification by numerical simulation of proposed mitigation arrangements, which were successfully implemented onsite.

Technical assistance related to electromagnetic transient modelling – Confidential client. Provision of technical assistance related to electromagnetic transient modelling of two offshore windfarm projects. Input to technical discussions with power systems studies contractor, review of models, and report deliverables. Modelling issues identified with; tuning and numerical stability of frequency dependent cable models, calibration of frequency dependent surge arrester models, treatment of three winding transformers, selection of saturation parameters for large transformers, control of STATCOM units, calculation of zero sequence impedance parameters; assessment of zero-missing phenomena for reactor compensated cables, and assessment of sympathetic inrush between transformers.
