The HV Asset Manual is the go-to document explaining how all the systems work showing parameter settings and technical data all in one document, referring to key drawings and documents located within the document management system. Typical structure is as follows:

Primary and Secondary Equipment

• System location and nomenclature as per SLD
• Brief technical description
• Brief technical data sheet tables
• Reference documents
• Design technical specification
• O&M Manual (s)
• Technical Files (containing FAT and Commissioning Results)

Protection Equipment – Brief Technical Description

• Relay Settings
• Protection Philosophy
• Thermal settings (transformers and SVC Plus equipment)

HV and LV Power System Modelling

• Power System Reactive Power and Active Power Flow Studies
• Reactive Power Flow Optimisation Studies
• SVC (Static Var Compensation) modelling and optimisation
• Protection Co-ordination Studies
• Circuit Breaker and Protection Tripping Investigations
• Protection Settings Checks

Failure Investigations

• Cable and Termination Failure Investigations

Designing offshore wind projects entails various stages which are intended to enhance and perfect the overall power system design. This process aims to reduce project uncertainties by enhancing the functionality and efficiency of your electrical assets.

Due to the high capital expenditure costs associated with renewable generation technology, EPS can provide you with a cost-effective electrical design for your installation. Typical documentation EPS has provided to previous renewable energy installations includes:

• Design & Installation of DTS cable monitoring systems.
• Substation and plant layout drawings.
• Electrical protection calculations for both LV and HV equipment.
• Substation lighting and small power supplies.
• Earthing and lightning conductor design.
• High Voltage and Low Voltage equipment specifications.
• Cable routing drawings.
• Cable calculations for both low-voltage and high-voltage cable networks.
• Bill of Materials.
• Project capital cost estimates.

EPS’s Offshore Renewables Approach

Using electrical engineering software ETAP, ERACs, IPSA or DigSILENT, our electrical engineers can provide you with a study report for your power system.

Whether it’s a power system study for the entire wind farm or hydro-electrical distribution system, or a modification/ addition to the electrical system EPS can provide you with the following technical services:

Power System Modelling & Investigative Analysis

Typical Studies include:

• Transformer Energisation Studies.
• Load Flow Analysis Studies.
• Short Circuit Studies.
• Transient Motor Starting Studies.
• Harmonic Analysis.
• Protection Co-ordination.
• Arc Flash Assessments and Switchgear Risk Assessments.

• Attend meeting with the DNO (Distributed Network Operator), SSE, Scottish Hydro, Northern Powergrid, Western Power etc.
• Provide solutions to grid connection issues.
• Offshore and Onshore surveys.
• Factory Acceptance Testing.
• Mechanical and electrical thermal imaging reports for wind turbine machinery, gearboxes, braking systems, generator, electrical equipment (onshore and offshore).
