A Brief Discussion on the Generator Grid Connection Breaker System
Power plants often use generators as backup power sources to cope with power outages in the grid, failures of power supply equipment, and equipment maintenance. When a power outage occurs, the generator should automatically start within a few seconds to supply power to the feeder cabinet and elec...Read more -
Measures for controlling noise
(1). Aerodynamic Noise Control: 1. Intake Noise Control: Most engines are equipped with air filters, which can significantly reduce intake noise and make it a secondary sound source. However, when other sound sources are further controlled, intake noise may become the main sound source. At this p...Read more -
Analysis of Noise Causes of Diesel Generator Sets
Diesel engine noise is a complex sound source composed of multiple sound sources. According to the radiation mode of the noise, diesel engine noise can be divided into air dynamic noise and surface radiation noise. According to the mechanism of generation, diesel engine surface radiation noise ca...Read more -
Explanation of Parallel Operation of Three-Phase Generators
The parallel operation of three-phase generators requires that in the circuit formed by connecting the generators to the grid, no inrush current should be generated. The following conditions must be met: (1) The voltages of the generators should be the same in magnitude and phase; (2) The frequen...Read more -
Precautions for Design and Installation of Diesel Generator Rooms
Precautions for Design and Installation of Diesel Generator Rooms I. Foundation 1. Support the entire weight of the generator set 2. Maintain the installation positions of the engine, generator and auxiliary equipment 3. Isolate the vibration of the generator set from the surrounding structure 4....Read more -
Diesel generator
Diesel generator is a generator driven by an internal combustion engine. It starts quickly and is easy to operate. However, the cost of generating electricity by an internal combustion engine is relatively high, so diesel generator sets are mainly used as emergency backup power sources, or in mob...Read more -
Synchronous Generator
A synchronous motor operating as a generator. It is a commonly used alternating current generator. In modern power industry, it is widely used in hydropower generation, thermal power generation, nuclear power generation, and diesel engine power generation. Since synchronous generators generally u...Read more -
What are the rated parameters of a synchronous generator?
The main rated electrical parameters of a synchronous generator are: (1) Rated power (pe) refers to the rated active power that the generator can output under rated operating conditions, measured in kilowatts (kW) or megawatts (MW). (2) Rated voltage (Ue) refers to the line voltage of the genera...Read more -
Which items need to be verified before operating a diesel generator set
Today, the technicians of Beidou Power Generator Company will summarize for everyone the three aspects that the operators must confirm before the operation of the newly taken over diesel generator set. The specific details are as follows: Verify which self-protection functions the diesel generat...Read more -
The external characteristics of synchronous generators
The external characteristics of a synchronous generator generally refer to the curve of the voltage variation at the generator terminal when the load current changes while the internal electromotive force remains constant. The main test is the longitudinal axis synchronous reactance of the genera...Read more -
Fault Diagnosis and Elimination of Synchronous generators
1. The generator is overheating (1) The generator did not operate in accordance with the prescribed technical conditions, such as the stator voltage being too high and the iron loss increasing; When the load current is too large, the copper loss of the stator winding increases. The frequen...Read more -
The structure and principle of synchronous generators
1. Structure The synchronous generator is mainly composed of the stator, rotor and other components. The stator part includes the stator core, stator winding, and frame; the rotor part includes the rotor core, excitation winding and slip rings (for the hidden-pole rotor, there are also sleeve and...Read more
