The basis for the purchase of diesel generator sets

3. Common diesel generator set speed determined

In order to reduce wear and increase the service life of the unit, should use common turbines rated speed of not more than 1000r / min, the low-speed unit, its optional standby unit, the high-speed unit. The same power plant units should use the same model, with the capacity of the unit in order to use the same spare parts, easy maintenance and management. Load changes of project, you can use the same series of units of different capacities. Generator output voltage to determine the calibration and emergency generators same, usually 400V, individual electricity capacity, transmission distance of high pressure turbine engineering can be used.

4. Common control diesel generator set


Common Units should generally be considered capable of parallel conduct to simplify power distribution main wiring, the unit start, stop rotation running through and cars, load transfer, switching power supply unit without interruption. Units should be fitted with measurement and control devices of the unit, the governor and excitation unit adjusting device shall be carried out in parallel with the applicable requirements of fish. Important load power supply standby generator sets, diesel generator sets should use automated external power failure after power failure, can quickly start automatically restore power to the important load. Engine running room noisy, automation unit to facilitate the transformation of the compartment, automatic monitoring of generator sets. When the generator set normally, the operator does not have to enter the diesel engine room, the control room can be monitored on the diesel generator.
