Permanent Magnet Synchronous Generator (PMSG) in Wind Power Plant
A Permanent Magnet Alternator is an electric generator that is used to convert mechanical energy to AC electrical energy. The use of a permanent magnet in place of a field coil is a distinct new process that has grown in popularity over the years. High-quality permanent magnet alternators are increasingly being deployed in modern technological […]
Causes, Hazards, and Treatment of Generator Rotor Grounding
The grounding of the rotor of the generator has one-point grounding and two-point grounding of the rotor. In addition, there will be short circuit faults between rotor layers and turns. Like stator grounding, rotor grounding can be divided into instantaneous grounding, intermittent grounding, permanent grounding, internal grounding and external grounding, metallic grounding, and resistive grounding. […]
The Difference Between On-Grid And Off-Grid Permanent Magnet Wind Turbines
The grid-connected permanent magnet direct-driven wind turbine is a new type of power generation technology, which uses wind power to convert the torque of the unit into electrical energy, and then outputs the electrical energy to the grid. The permanent magnet direct drive wind turbine is a special generator set that uses a generator made […]
Understanding wind power grid connection
01. What is a wind power grid connection? There are two different types of wind power: 1. Independent operation – off-grid type: Off-grid wind power generation is small in scale, and it is combined with energy storage devices such as batteries or combined with other energy generation technologies (such as wind power/hydropower complementary system, wind […]
Effects of Generator Demagnetization
The influence of generator loss of excitation on the system mainly includes: 1. Generators with low excitation and loss of excitation absorb reactive power from the system, causing the voltage of the power system to drop. If the reactive power reserve in the power system is insufficient, the voltage at some adjacent points in the […]
The Social Significance of Permanent Magnet Generator
I. Introduction – Briefly introduce the concept of permanent magnet generators (PMGs) Permanent magnet generators (PMGs) are electrical machines that convert mechanical energy into electrical energy using the principle of electromagnetic induction. Unlike traditional generators that use electromagnets, PMGs use permanent magnets to create a constant magnetic field. The basic working principle of a PMG […]
