Reference: NIA_SPT_1310

Status: Complete

Start Date: Mar 2014

End Date: Jul 2014

Funding Licencee(s): SP Energy Networks and SP Transmission

Contact: James Yu (Future Networks Manager)

Funding Mechanism Network Innovation Allowance

Research Area: None

Core Technology(ies): Voltage Control

Estimated Expenditure: £48,000.00

Introduction: Initially, the focus of the project will be on the switching of 33kV rated shunt reactors (based on the cost and existing experimental facilities), but other voltage levels may be considered.

Objectives:

Develop guidelines for reactor switching transient recovery voltage (TRV) simulations at 33kV (and other voltages )

Make recommendations for circuit breaker rating and mitigation options for inclusion in a company policy document.

If the outcomes are useful, there could be the possibility of extending the project to cover higher voltages and series reactors.

Expected Benefits: This project will be deemed successful if a more economical solution is determined for reactor switching.
