gen kw & kvar sharing problem
gen kw & kvar sharing problem
(OP)
hello guys! i need some technical advice about our generators problems. we got 3 gen rated 230 kw each using mechanical governor, brushless self excitation. if 2 gen are in parallel, the sharing of kw not continously stable. sometimes ok then after several mins the diff is too big, say 45 kw. we taried to load 100% and the sharing of kw & kvar found ok,, say 230/228 kw, but sometimes the diff becoming bigger. any thoughts about it. thanks in advance.

Or, if a governor has some sticktion it may not be noticable running alone but have issues running in parallel.

How are you measuring KW?
What is your load?
Occasionally a new set will have an air leak between the day tank and the fuel pump. It sucks a little air and you get air bubbles in the fuel. A restricted fuel filter or air bubbles on one set may lead to the other set taking too much load.
Both sets should run the same frequency unloaded typically 61.8 Hz or 51.5 Hz. Both should run at 60 Hz or 50 Hz at full load.
If the sets initially share the load well, the settings are probably good.
