The Smart Street project, submitted as a Tier 2 Bid to the LCN Fund competition by Electricity North West, was awarded funding in November 2013, and will formally commence in January 2014. Kelvatek are a key partner in the four year Smart Street project, having developed technology that will allow the project to be applied to trials on Electricity North West’s distribution networks.
The project will employ innovative voltage control using alternative network configurations to show that a Distribution Network Operator (DNO) can increase the capacity and voltage headroom available for Low Carbon Technology, lower network losses and reduce overall energy consumption. The techniques and technology demonstrated will provide a robust template for the DNOs in Great Britain.
Part of the project will look at interconnecting Low Voltage (LV) networks. Safely transforming a radial LV network into an interconnected LV network requires that traditional ‘J’ type fuses at distribution substations and link boxes need to be replaced with intelligent switching devices.
Kelvatek have developed new controllable and configurable retrofit vacuum switching devices, called the WEEZAP and LYNX, for insertion into existing LV fuse ways on an LV distribution board and link boxes. The devices can be remotely controlled allowing both sensing of feeder flows and dynamic reconfiguration of the LV network. The devices are integrated into the automation software in Electricity North West’s Network Management System facilitating additional benefits such as network resilience. This will be the first demonstration in the UK of a fully centralised LV network management (and automation) system.
