Along with the generators, the historic Vranovské dam energy station now has batteries – Information

The set up of batteries within the constructing of the ability plant is exclusive. As a substitute of storing them in a container, the corporate E.ON, which operates an eighty-year-old energy plant, selected a brand new answer. Though extra complicated and troublesome to put in, it displays the historic look of the dam embankment. Getting the batteries into the constructing was a job that examined designers and craftsmen alike.

Till lately, the corporate’s distributors, in line with the necessities of the operator of the Czech transmission system, modified the move of water via the generators each minute to match the manufacturing of electrical energy with the present consumption. The necessity for such therapy has elevated and continues to extend with the set up of photo voltaic and wind farms, whose output relies on daylight or wind power and can’t be managed. administration This can be a downside for vitality distribution throughout Europe, 1 / 4 of the vitality consumed final 12 months got here from renewable sources.

When it’s inconceivable to affect the manufacturing values ​​of photo voltaic and wind vitality, it’s essential to stability the variations between consumption and manufacturing going to hydropower vegetation via adjustments within the efficiency of generators , or by connecting and connecting them. Nevertheless, frequent adjustments within the system’s efficiency and connectivity can considerably put on down the system’s mechanical parts. As well as, the change doesn’t come instantly, however with a sure delay. Connecting battery storage to the system is a quicker answer, each in a state of affairs the place extra vitality must be equipped to the community or, however, it’s crucial to produce an excessive amount of vitality go and retailer in batteries.

“A battery with a usable capability of two and a half megawatt-hours can, if crucial, be absolutely engaged in energy balancing companies inside 5 seconds and assist preserve stability and reliability the distribution community,” mentioned E.ON firm spokesman Lubomír Budný. The gear didn’t find yourself in containers someplace close to the 90-year-old dam, however discovered a correct place within the energy plant constructing. The development prices of practically sixty million crowns.

“We needed to make adjustments to the constructing, strengthen the ground and the roof to help the battery cells,” mentioned Siemens firm supervisor Zbyněk Orság. Batteries, management gear, the place direct present electrical energy with a voltage of 949 volts is first transformed to a different present with a voltage of 560 volts, and at last, after transformation to 6300 volts, enters the transmission system. “All of the units are below the management of the management room, which retains them remotely from Brno,” mentioned Orság.

The batteries have excellent hearth safety, a system with two safes would launch nitrogen into the battery compartment in a fireproof focus if there was a hearth sign. The electronics rigorously monitor the state of affairs within the battery chamber and consider any adjustments. “Pure nitrogen belongs to pure gases and has no unfavourable impression on the surroundings. The fireplace extinguishing system extinguishes any hearth on the level of origin and is exclusive in its essence,” mentioned Tomáš Hüner, director of Siemens Sensible Infrastructure Czech Republic.
