| Power plant products New modular synchronous generator
ABB has developed its new 20 MW class synchronous generator, designated ‘Modular’ as a flexible, scalable approach to balance power grids as they cope with increasing volumes of renewable energy. In contrast to previous designs intended for continuous output only, the modular platform can be configured for various operational profiles. These range from short-term, peak shaving, through intermediate operation to traditional, continuous baseload generation. The new synchronous generator also offers the capability to increase the inertia available by incorporating flywheels.
Generating sets often need to meet country- specific grid code requirements before they may be connected to electricity networks and the Modular unit comes fully grid-code compliant. Another demanding requirement is to stay connected during a low voltage or short-circuit event in some part of the grid. This calls for high inertia to ensure that the plant stays synchronised with the grid when the fault is cleared, and voltage returns to nominal. To support this requirement, the Modular synchronous generator has an option to add inertia by incorporating additional flywheels.
Modular construction, together with ABB’s extensive global supply chain, enables the new generator to be delivered within shortened timescales. It is also designed to support easy transportation and installation
Using the Modular synchronous generator in peak-shaving or intermittent operational profiles typically means that the running hours are shorter compared to traditional continuous operation. This reduces the demand for cooling. Therefore, the new design also features an upgraded cooling unit which can be operated only as needed.
Scoping reports submitted for Stromar offshore wind farm
Stromar Offshore Wind Farm, a joint venture of Ørsted, BlueFloat Energy and Renantis, has successfully submitted its comprehensive EIA scoping and HRA screening reports to the Marine Directorate and Aberdeenshire Council for the offshore and onshore aspects of its 1 GW floating offshore wind energy project.
Lidar units used for site assessment
Stromar, which is located approximately 50 km east of Wick off the north coast of Scotland, is expected to make a significant contribution to the Scottish and UK governments’ net zero targets, and to create job opportunities, stimulate economic growth, and bolster the local supply chain.
The EIA (environmental impact assessment) scoping reports outline the plans for the development, addressing both onshore and offshore considerations. The HRA screening (Habitats Regulations Assessment) reports outline the key protected sites and species of relevance to the development area and present how impacts will be assessed in more detail at the next stage. The project team will now schedule a number of community consultation events during spring 2024 to ensure stakeholders are fully informed and that their views are considered in the site selection, design and development of the project.
Boiler rebuild for Steven’s Croft biomass PP
Valmet has contracted to deliver a major boiler rebuild to E.ON’s Steven’s Croft biomass power station in Lockerbie, Scotland. The value of the order, to be fulfilled during the second quarter of 2024, has not been disclosed.
Steven’s Croft’s bubbling fluidised bed (BFB) boiler, originally delivered by Valmet, was started up in 2008. With good maintenance and regular
refurbishments, the boiler’s performance has been kept at a high level. Now, the boiler is to undergo a thorough refit involving replacement of its major components.
“For 16 years, E.ON Steven’s Croft has been providing a low-carbon power and heat solution to the local area, and central to this is the Valmet BFB boiler” says Scott Robinson, site manager at
Steven’s Croft.
Valmet’s delivery will include renewing several key components of the power station’s bubbling fluidised bed (BFB) boiler such as the primary superheater, economisers, primary air preheater and screen tubes. Special corrosion resistant material will be used where applicable to prolong the lifetime of the parts.
