    Diesel Standby Generator - Life Expectancy

    If You mean 50 years with replacing all spares and maintenance as per run-hours only - then NO. You will get big troubles already after 2-3 years of operation. Its many spares and maintenance services that You have to do either by run-hours or by standby time if its standby unit. You should...

    lithium ion batteries

    Its strongly recomended not to discharge fully LiOH or Li-ion cells. Usually controllers for such batteries are smart enough to keep proper float charge voltage, so it is no reason to keep your device discharging, just for preventing overcharging. Full discharge will decrease your battery...

    AVR Basler DECS200(redundancy), VARs moving

    Thanks for response, Mikel. I think, they just design it only for running in parallel.. So base load was using as a temporary mode, while genset was syncing to gas turbine generator (MAIN SUPPLY). Then, once breaker for GTG open, second diesel sync with first, and DEIF switchs to Load sharing...

    AVR Basler DECS200(redundancy), VARs moving

    Hi again.. This DEIF GPC2 controller... I have rechecked drawings and found interesting thing. It has modes for governor (fixed F, base load, droop, load sharing), and for AVR (fixed V, fixed VAR, fixed PF, VAR sharing).. By drawings, its always fixed voltage modes for both engine. For governors...

    Diesel engine can not give more than half load

    That governor 723plus has jumper on terminals 9-10. This terminals is for LOAD SHARING SIGNAL. I have checked many manuals of Woodward 723+, but didnt found purpose of jumper. If i do not need load sharing, should it be jumped or remained open? Viktor Electrical Technician II

    Diesel engine can not give more than half load

    Well, genset is discussed one, and loads - a lot of 400V UPS, motors, any domestics.. Plus 11KV 250KW air compressor motors. We need at least 2 unit running. Due to our frequency dropping too high, usually when we start second big motor, we getting underfrequency trip. So our practice now, we...

    I mean best combo for stability during dynamic loads switching ON. Viktor Electrical Technician II

    Diesel engine can not give more than half load

    Thanks for links and file! I have read it before, and now understand separate functions of droop and iso, but what is the best combo for single genset? And what is the best combo for 2 parallel gensets? Just refer to your experience. Without grid. Viktor Electrical Technician II

    Diesel engine can not give more than half load

    One more question, how engine perform: 1) If AVR and Governor in Droop mode 2) If AVR no droop, and Governor Droop 3) If AVR droop, but Governor not. Is it major changes will be? Viktor Electrical Technician II

    AVR Basler DECS200(redundancy), VARs moving

    Thanks Mikel, for sharing Your experience. I think we stop here, since I heard the possibilities, but cannt check it on practice. At least next time I will know what to do. Viktor Electrical Technician II

    Diesel engine can not give more than half load

    I agree. Today my last night shift, after 2 weeks I am going to day shift, and my goal will be to get approval for load test. Anyway, I have learnt much during this troubleshooting, thanks for You all! Once any update or results, I will write here. Viktor Electrical Technician II

    AVR Basler DECS200(redundancy), VARs moving

    DEIF Multi Line 2. It was using for constant control of parallel work two gensets, without grid. DECS was AVR mode with 3% droop. Now I dont have access to them (however I still keeps docs and reports of it), but I just wondering to know was it problem, or no. It was "my small frog, which I had...

    Diesel engine can not give more than half load

    MAP sensor we checked, its working well on different pressures. Do you think 5 point is must, if this two configure lines shows: CONFIGURE: Z10: CFIG OPTION.USE 5-GAIN MAP 0 CONFIGURE: Z10: CFIG OPTION.USE CONST DYNAMICS 1 BTW, today we did no-load testrun with open port of turbocharger inlet...

    Generator frequency jumping on 50%+ load

    BTW, should AVR be in same droop mode, as governor? How it can reflect to load efficiency, if for example AVR has no droop, but governor is 4% droop? Viktor Electrical Technician II
