Abstract:

The use of direct-drive permanent magnet (PM) generators for MW wind application is increasing, because they have higher reliability and less maintenance than geared generators such as geared PM generators and geared induction generators. The price of the direct-drive PM generator is high, taking 10%-15% price of its overall system. Therefore, the generator mush be safely operated to have a long life. For a PM generator, its performance is sensitive to ambient and working temperature so that it needs to be monitored. In this paper, a method is proposed, combining the practical knowledge of a g

Abstract:

Self-excited induction generators are a specific form of three-phase induction generators that were frequently used for generating electricity in remote locations that had no access to the main power grid. The generator was commonly connected to different electrical loads, such as light bulbs, which were classified as resistive loads. However, because of its non-linear nature, the use of rectifiers can generate harmonic currents, leading to voltage distortion. Hence, this study performed a comparative analysis of the attributes of a self-excited three-phase generator operating with a resistive

Abstract:

One of the alternative generators in supplying electrical energy is a 3-phase generator made from a 3-phase slip ring induction motor, after which the rotor winding is supplied with a DC source and rotated using a prime mover. The problem arises because of the large % voltage regulation of a 3-phase generator when it is under load. This is because the induction generator has a relatively larger voltage loss when loaded with a certain load compared to a 3-phase synchronous generator. To overcome these conditions, there are several ways that can be used to stabilize the voltage from the generato

Abstract:

Synchronous generators work by changing mechanical energy into 1 and 3 phase electrical energy. Reactive power is needed by consumers to generate magnetic fields in inductive electrical loads. The reactive power setting can be adjusted by increasing or decreasing the excitation current. Excitation current is a DC electric current that is supplied to the generator rotor to generate a magnetic field. The excitation current is proportional to the reactive power released by the generator. This is indicated by the increase in the reactive power of the generator which was initially valued at 0.6999

Abstract:

Alternative energy are need for the energy crisis that has occurred recently, one of the efforts to create alternative energy is by using wind, the energy obtained from the wind is converted into a generator. In general, generators produce voltage at quite high rpm, and also require exciter current for the trigger current to produce voltage. The aim of this research is to design a generator to obtain a constant voltage with low rotation, so a low speed generator is needed, namely the Axial Flux Permanent Magnet (AFPM) Generator.

Abstract:

Abstract Self-excitation for synchronous generator is described in the paper. The system is based on a buck converter input filter capacitor discharge through excitation winding of the generator. The buck converter is connected to the stator outputs through an uncontrollable diode rectifier, but excitation winding is used as a load. Input filter capacitor of the converter provides initial current pulse which magnetizes excitation system and produces the generator voltage increase, for this reason the capacitor is charged before self-excitation process starts.

Abstract:

The inherent differences between salient and nonsalient electrical machines are evaluated for two permanent magnet generators with different configurations. The neodymium based (NdFeB) permanent magnets (PMs) in a generator are substituted with ferrite magnets and the characteristics of the NdFeB generator and the ferrite generator are compared through FEM simulations. The NdFeB generator is a nonsalient generator, whereas the ferrite machine is a salient-pole generator, with small saliency. The two generators have almost identical properties at rated load operation. However, at overload the b

In this study, it is proposed to develop a voltage control on the generator, in order to produce a fairly controllable and reliable voltage, with an analog circuit using a multistage comparator. Control of the generator output voltage is carried out by adjusting the field current from a separate voltage source which is forwarded to the resistance which is regulated based on the generator output voltage level with a multilevel comparison system.

Power is generated in a variety of ways, including renewable energy, nuclear power, and burning of fossil fuels. The majority of our power is currently generated by burning fossil fuels, mostly natural gas and coal, to spin turbines attached to an electromagnetic generator. The main advantage of AC generation is that the voltage levels can be altered up and down with transformers, allowing electricity to be sent across long distances to the loads that demand it. The excitation system demand for large synchronous generators with a few hundred-megawatt ratings becomes very enormous. The challeng

Abstract:

Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of an IBR is affected by the current limitation, the synchronization of the synchronous machine simulated virtually inside the IBR controller with the other synchronous generators in the grid is affected, which may cause step-out of the simulated generator. We propose a methodology which can keep the synchronization by modifying internal induced
