Shaft generators for low speed main engines
If the generator is connected to the grid via a frequency converter, the mechanical torque from the generator is inversely proportional to the engine speed required to maintain constant electric power,
If the generator is connected to the grid via a frequency converter, the mechanical torque from the generator is inversely proportional to the engine speed required to maintain constant electric power,
Due consideration must be afforded by the ship''s design engineers to the paralleling of the shaft generators with the ship''s electrical system, ensuring voltage, phase and frequency is matching.
Generator synchronization on ships is the process of matching the electrical
The Proportional-Integral-Derivative (PID) control technique, with advantages such as simple design and fast response, is widely applied in the maritime industry. However, determining
The alternator output parameters and specification for power output, voltage, frequency and speed etc. are required for the alternator when operating as a shaft generator in PTO mode of operation.
Due consideration must be afforded by the ship''s design engineers to the paralleling of the shaft generators with the ship''s electrical system, ensuring voltage, phase and frequency is matching.
Below is a list of some not-so-commonly-known constructional features of marine generators and some overlooked but important generator procedures that are often not discussed or
Generator synchronization on ships is the process of matching the electrical parameters—such as voltage, frequency, and phase —of two or more generators before connecting them to a common
In order for the generator to work properly, it requires maintenance and must always be well controlled, so that the parameters generated by the generator must always be maintained by...
They include parameters such as load factor, operational hours, and overload capabilities. These ratings help in selecting the right generator for standby, prime, continuous, or marine applications.
The parameters obtained may be applied to specify the ratio for exhaust gas emission, to compare fuel consumption for various methods of generating electricity and to assess the possibilities to use the
The shaft generator drive can operate in a variety of modes, each one bringing new functionalities that have an impact on ship operations and their associated costs:
