About the Project
Issues linked to the progressive closure of synchronous generation plants in thermal power stations include:
The closure of these large synchronous generating plants is reducing overall inertia within the GB network. Phoenix will demonstrate how inertia can be reintroduced.
Voltage control is becoming limited as synchronous generating plant is used for this. Phoenix will provide more control over voltage in the network within its capability.
- Lower Short Circuit Level
Short circuit level is important as it is needed to operate protection correctly. The loss of large generating plant reduces short circuit level, meaning electrical protection may not operate.
By bringing two technologies together to create a Hybrid- Synchronous Condenser, the Phoenix project will provide a more stable system, reduce costs - bringing benefits to customers and aiding the move towards cleaner energy.
Phoenix will provide more control over voltage in the network within its capability.
The roll-out of Synchronised Condensers will help create stability in the grid, reacting when extra power is needed and providing more control over voltage. However, there is a range of technical, commercial and engineering issues that have to be addressed first.
Phoenix is an innovative project which aims to overcome those issues by combining two technologies: Synchronous Condensers and Static Compensators. The result is a Hybrid-Synchronous Condenser.
The objectives of Phoenix are to demonstrate a sustainable design, deployment and operational control of a Synchronous Compensator with innovative hybrid co-ordinated control system combined with a static compensator referred to in the project as Hybrid-Synchronous Compensator.
The objectives of utilising these devices is expected to demonstrate how the serious system issues that are being encountered on the GB transmission network as a result of the progressive closure of synchronous generation plants can be mitigated
Phoenix will enable future installations and essential network services to be provided for GB System Operators, Transmission Owners and Distribution Network Operator.
Phoenix will consider the wider market and how a market could be structured to deliver the services including inertia and short circuit level.
The Benefits For Customers
In comparison to the conventional synchronous generators currently in place and closing, Phoenix will:
