When reliability meets sustainabilityGenerator Circuit-Breakers (GCB) are key components to improve the reliability and protection of your paramount power unit equipment such as generators and step-up transformers. Their installation leads to higher power plant selectivity, increased availability, together with simplification of the operational procedures and a reduction of the overall costs. With Siemens, your retrofit and new power plant projects will be supported by one of the most experienced partner in Generator Circuit-Breaker solution. Dedicated to deliver durable and reliable solution, Siemens has been systematically advancing generator switchgear with vacuum switching technology providing our customer with proven SF6- and maintenance-free vacuum technology.
What are GCBs used for? Discover their benefits
Waste-to-energy power plants convert sources of waste into heat. Operators use the heat generated in this incineration process to produce electricity and district heat. High power plant selectivity is needed!
Geothermal power plants use hydrothermal resources from the depths of the earth. The hot water or steam powers a turbine to produce renewable electrical energy. It requires powerful and reliable components, seamlessly integrated and with optimum availability
In Thermal power-plant, the waste heat produced in a plant facility is used in other industrial processes, extracted to cover the heat demand of individual buildings, or distributed to a district heating system.
In combined cycle power plants (CCPP) a gas turbine generator generates electricity while the waste heat from the gas turbine is used to produce steam to generate additional electricity via a steam turbine.
The latest technology achieves unprecedented efficiency levels of more than 60 percent.
Hydroelectric power plants use energy of water to drive a turbine and must be sustainable to protect the environment.
They need to be efficient and available for a long time before refurbishment.
Synchronous condensers are machines designed to provide inertia and short-circuit power by means of rotating mass while also providing or absorbing reactive power for dynamic loads.
With the increasing penetration of nonsynchronous generators (wind turbine, photovoltaics, and battery storage system), synchronous condensers are proven solution to stabilize the grid.
Our GCBs are built to operate numerous times a day with utmost reliability thanks to a full-spring operating mechanism with a lifespan up to 20,000 CO operations.
• less operational expenses
• less maintenance effort
• less outage
Our GCBs are tailored to individual requirements and deliver the most reliable full-spring operating mechanism to stabilize the grid
• High reliability
• Reduced carbon footprint with vacuum technology
• less maintenance effort
Pumped storage power plants (PSPP) are proven methods available for grid-scale energy storage. They are needed in areas with high installed capacities of wind parks and solar power plants to significantly support grid reliability. To that end, the availability of the power plant must be high to provide energy during peak demand.
