    Load sharing - Communication

    We are using DEIF IE350 for load sharing/paralleling of the generators. What is the best communication method for load sharing, there is a RJ 45 port and there is a CAN bus.

    Keyboard and Mouse

    Sorry, dumb question, even though Touch panel is provided, why mouse and key is provided in some control panels?

    25A - Synchronizer

    Why some auto synchronizers are provided with only ability to adjust the speed and not the voltage? In which case synchronizers with ability to adjust only speed is used? and In which case, synchronizers with ability to adjust both speed and voltage is used?

    Isochronous load sharing lines - Dissimilar Generators

    Is it practically feasible to successfully test, commission, and operate isochronous load sharing lines for load sharing between one steam turbine generator (STG - 1.5MW) and three diesel engine–driven generators (3.5MW), given that the generators are dissimilar? Normally the steam turbine...

    Parallel running of dissimilar generators with different droop settings

    Thank you for the detailed explanation as usual! say, when the EDG is running at part load or fixed power, in parallel with other generators, if some loads are added/removed, because of this, system frequency is reduced/increased, then the machine running at part load will increase/decrease the...

    Parallel running of dissimilar generators with different droop settings

    Is the "Fixed kW" control then a droop control with an aim to keep the ERROR constant?

    Parallel running of dissimilar generators with different droop settings

    As I understand then, keeping the machines with different droop settings will become a concern when starting /stopping large loads, Now thinking to operate the emergency generator should operate in fixed kW mode and the other generators in droop based on the Emergency tie breaker status; if the...

    Isolated Generator and Droop Governor

    As I read the datasheet, the engine has a electronic governor so it should have capability to operate both in Isochronous/droop; so the target is if the Emergency tie breaker is closed, the emergency generator should operate in fixed kW mode and if the tie breaker is open, the emergency...

    Parallel running of dissimilar generators with different droop settings

    1. Yes, DG3 is emergency generator The parallel operation is only done during testing or Non emergency mode so that machine can be loaded fully and clean the soot deposits 2. The other two generators will be running in parallel in droop mode with external control from PMS

    Isolated Generator and Droop Governor

    How do I know that if the Diesel engine governor is equipped with only Isochronous capability, droop capability or is it capable of fixed kW? or both? Say, I would like to operate all three generators (two large units and one smaller unit in parallel) while running in island mode. The small...

    Parallel running of dissimilar generators with different droop settings

    In this setup, is it possible to operate all three generators in parallel by configuring DG-1, DG-2, and the STG in Droop mode, while operating DG-3 in Fixed kW mode? The manufacturer claims that DG-3 cannot run in parallel with 11kV generators, citing a mismatch in droop settings: the maximum...

    Rotor earth fault for Diesel generators

    What are the methods for detecting earth faults in rotor windings without using slip rings? This is for diesel generators with a capacity of 3 to 5 MVA. Is it possible to use instruments like Brush Prismic R10 Rotor earth fault monitor for these generators (3 to 5MVA). What are the disadvantages...

    CT and VT Location in the Generator Terminal Box

    I have some questions regarding the CT & VT location in the generator terminal box, 1. Droop CT location before the star point at the neutral side of the generator (or) can be at the line side? 2. Why AVR VT sensing has to be taken from the line side and not from the neutral end? 3. What is the...

    Main Generator, Auxiliary Generator or Essential Generator in a Tanker ship

    We have three diesel generators that operate in parallel with a steam turbine generator (STG) on a tanker, of course there is a Main Engine. The excess steam generated from the heat value of VOC gases during cargo loading operations is utilized to drive the steam turbine generator (STG). Should...
