Yes and no. One generator may be operating in the leading VAR region, and the other may be operating in the lagging VAR region. This would result in reactive current effectively circulating between the two generators.
If you are talking about active (real) power, this should not happen, and will cause protective equipment to trip. Generators should generate real power, not consume it.
What else can I help you with?
Is it diesel generators is DC or AC generators?
Most diesel generators are designed to produce alternating current (AC) electricity. However, there are some diesel generators that can also produce direct current (DC) electricity with the help of rectifiers or inverters.
Do generators supply direct current?
Yes. Alternators supply alternating current.
How the current flow in parallel connection?
In a parallel circuit, the current flow is independent in each branch.
What is the formula of load calculation?
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.
What are equalizer rings used for?
An equalizer, or equalizer connection, connects two or more generators operating in parallel at a point where the armature and series-field leads join (see Fig. 7.13), thusconnecting the armatures in multiple and the series coils in multiple so that the load will divide between the generators in proportion to their capacities. The arrangement of connections to a switchboard (Westinghouse Electric Corp.) is illustrated in Fig. 7.14. Consider, for example, two overcompound-wound machines operating in parallel without an equalizer. If for some reason there is a light increase in the speed of one machine, it will take more than its share of load. The increased current flowing through its series field will strengthen the magnetism, raise the voltage, and cause the machine to carry a still greater amount until it carries the entire load. When equalizers are used, the current flowing through each series coil is inversely proportional to the resistance of the series-coil circuit and is independent of the load on any machine; consequently, an increase of voltage on one machine builds up the voltage of the other at the same time, so that the first machine cannot take all the load but will continue to share it in proper proportion with the other generators
What will happen if it does not met the parallel operation of a dc generator?
there will be circulating current between the generators sufficiently large that might damage the machines.
In parallel operation of diesel generators why one neutral contactor is used?
To avoid possible current loop through multiple neutral points
Why you need parallel operation of dc generator?
The generators also have resistance which causes power loss and voltage drops. Connecting them in parallel reduces the total resistance that reducing the voltage drop as well as increasing the total current.
What is the difference between shunt generators and series generators?
1. In Shunt generators armature current is equal to sum of field current and load current whereas in series generators field current and load current is same. 2. Shunt generators field winding has high resistance and large no of turns as compared to series generators. 3. Shunt generator field winding has thin conductor and series generator has thick.
Frequency voltage and amperage must be equal when ac generators are operated in parallel?
Frequency and voltage, yes. Amperage - desirable but not mandatory. Paralleled generators that are equally sized generally have a load balancing control that accomplishes this function. Generators that are of different ratings may be loaded to different current levels because of their capacity limitations.
What has the author Roman Krawec written?
Roman Krawec has written: 'General operating characteristics of a back-streaming direct-current plasma generator' -- subject(s): Magnetohydrodynamic generators
What are the Two types of generators that can be used to produce electricity?
The two main types of generators used to produce electricity are AC (alternating current) generators and DC (direct current) generators. AC generators are commonly used in power plants and homes, while DC generators are typically used in portable devices and certain industrial applications.
The electricity you get from batteries and generators is called?
Batteries and generators provide DC, Direct Current electricity.
What is the maximum power consumption of the appliance when operating at 230V 50Hz?
The maximum power consumption of the appliance when operating at 230V 50Hz is determined by multiplying the voltage (230V) by the current (in amperes) that the appliance draws. This calculation will give you the power consumption in watts.
Is it diesel generators is DC or AC generators?
Most diesel generators are designed to produce alternating current (AC) electricity. However, there are some diesel generators that can also produce direct current (DC) electricity with the help of rectifiers or inverters.
What is the star delta motors current calculation?
The calculation will change daily. You will have to check with the website to find out the current calculations for your needs.
Alternating current is produced by battery or generators?
A generator produces alternating current.
