Why Capacitor bank should be switched off when DG is in operation?

When generation kicks on, it can cause system voltage to rise, fall, or stay the same. Capacitors banks are used to help boost system voltage. Inductor banks are used to pull system voltage down.
In many situations, capacitor banks may be required to kick ON when generation kicks on - some wind turbines "suck in VARS", or act like inductors while pushing out power. This causes system voltage to sink, and must be counteracted using capacitors.
In your situation the distributed generation may be causing unacceptable voltage increases with the capacitor bank online.

Purpose of capacitor bank on a sub-station electrical room?
The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.
What are example of capacitive load?
capacitor bank
How do you connect the capacitor bank in electrical system?
improvement of power factor
How do you size a current limiting reactor for a capacitor bank?

Why capacitor bank not connected across Diesel generator power supply?
I dont know.... may be due to save money
Sir iam a working engineeri have come to a peculier problem the capacitor bank was installed at a sub-stationwhen capacitor bank is switched on the power factor becomes more lagging?
It's not peculiar. That's a property of capacitors.
What is the use of rvt in capacitor bank?
Use of rvt in capacitor bank
Why capacitor bank using reeactor?
Series reactors may be used in switching in capacitor banks. These are used to minimize the transient voltage spikes on the system resulting from switching in a capacitor bank.
How do you calculate Kwh saving after installing capacitor bank?
Adding a capacitor bank makes absolutely no difference whatsoever to the amount of energy consumed (in kilowatt hours). The capacitor bank might reduce the load current, but this does not affect the amount of energy consumed. Anyone who tries to sell you a 'capacitor bank' in order to save you energy is selling a SCAM!

How many current drawn in 400 kvar capacitor bank?
It depends upon at how much voltage level 400 kvar capacitor bank is used.
How does a plug in PFC differ from a capacitor bank?
It doesn't ?
How can be determined the rating of capacitor bank?
If you are talking about a capacitor bank used for power-factor improvement, then it is rated in reactive volt amperes (var). Otherwise, it is rated in farads (F).
What is the correct cable size for the 550 KVAR capacitor bank?
Cable sizing is based on amperage of the load. The rating of the capacitor bank and the voltage at which it operated need to be stated to give an answer.
How is hydroelectric energy stored for later use?
a capacitor bank
How much power of capacitor bank have to install for 100KVA?
If you want 100kVAR from a capacitor bank, you must install a 100kVAR capacitor bank. If what you're asking is related to how much capacitance it will take to offset a poor power factor, it is directly related to your load, and cannot be answered without more details - for power factor correction, you don't want to over correct (you would be buying too much equipment, and it could actually make your power factor look worse), so load profiles must be taken into account. Can the capacitors be switched on automatically, or must they be manually switched? What voltage level? The best way to determine this is to discuss with your local power company. They usually have people on staff that analyze this sort of thing on a regular basis, and if they don't, they could at least point you in the right direction.
