The client needed a competent contractor to install all necessary 275 kV plant to facilitate the connection of a Hybrid Synchronous Compensator (H-SC) at Neilston substation which is part of the Phoenix system security and synchronous compensator project.
As Principal Contractor, H&MV project managed the design and construction of the 275 kV plant to facilitate the connection of a Hybrid Synchronous Compensator
- H&MV Engineering project managed the design and construction of the new 275 kV bay.
- The new 275 kV bay was fed by teeing into the existing Windyhill/SGT2 mesh corner to provide the point of connection for the H-SC. This was achieved by installing a new bay comprising of a new circuit-breaker, rotating centre post disconnector including dual earth switches, current transformers, capacitive voltage transformers, combined current/voltage transformers, free standing earth switch, surge arrestors and post insulators. All modification of existing Windyhill/SGT2 mesh corner protection was also included in this project.
- The H-SC is being installed at Neilston substation to help stabilise the system from short circuit levels, system inertia & reactive power as the generation mix evolves to a higher penetration of renewables and the uncertainty over future availability of large generating plants in the UK.
- H&MV Engineering were responsible for issuing the Integrated Test Plans (ITPs), Construction Management Plans, Quality Plans, Safety Management Plan and Temporary Works Register
- Daily Toolbox Talks, weekly progress and safety meetings, issue and risk management along with monthly status reporting
- Project management and commissioning of electrical installation.
- Produce a complete set of electrical as-built drawings and a safety handover
