agregát

An agregát, in electrical engineering, is a self-contained unit that combines an internal combustion engine with an electrical generator to produce electricity. It is designed for standby power, portable or stationary use, providing electrical energy during outages, in remote locations, or at events where a fixed power supply is unavailable.

A typical agregát consists of an engine (usually diesel, gasoline, or natural gas) connected to a synchronous generator, with a control panel, fuel system, cooling system, exhaust, and lubrication circuit. The generator is regulated by an automatic voltage regulator to maintain stable voltage, while the engine speed determines the output frequency. Power output is commonly specified in kilowatts (kW) and kilovolt-amperes (kVA). Starting can be manual, electric, or automatic, and many units include an automatic transfer switch to switch electrical loads from the grid to the agregát when outages occur.

Types of agregáty include portable units (skid-mounted or wheeled), stationary or industrial units designed for continuous or semi-continuous operation, and specialized variants for marine, construction, or critical facilities such as hospitals or data centers. Typical applications are backup power for homes and businesses, temporary power on construction sites, event venues, telecommunications infrastructure, and remote facilities.

Safety and maintenance are essential. Adequate ventilation is required to prevent buildup of exhaust gases, and proper grounding and electrical insulation are necessary. Regular maintenance includes oil and filter changes, cooling system checks, air and fuel filter servicing, battery maintenance for electric starts, and periodic functional tests. Proper handling and storage of fuel, adherence to local regulations, and noise and emission controls are important considerations when deploying an agregát.
