Motor magnetic energy storage

Can superconducting magnetic energy storage cause voltage disturbance in traction power system?

However, the fluctuating characteristics of renewable energy can cause voltage disturbance in the traction power system, but high-speed maglevs have high requirements for power quality. This paper presents a novel scheme of a high-speed maglev power system using superconducting magnetic energy storage (SMES) and distributed renewable energy.

What is superconducting magnetic energy storage (SMES)?

During the braking of a maglev train, the regenerative power from the linear motor will cause high-amplitude overvoltage in the DC bus, which can severely impact the fragile traction power system [ 20 ]. Superconducting magnetic energy storage (SMES) is one of the most promising superconducting magnet applications.

Can superconducting magnetic energy storage improve power quality of high-speed maglevs?

Conclusions In this paper, a novel scheme was proposed for high-speed maglevs using superconducting magnetic energy storage and distributed renewable energy sources. The SMES compensation system was used to enhance the power quality of the maglev and ensure stable power supply during operation.

What are energy storage systems?

Energy storage systems (ESS) play an essential role in providing continuous and high-quality power. ESSs store intermittent renewable energy to create reliable micro-grids that run continuously and efficiently distribute electricity by balancing the supply and the load .

Why do electric motors need more energy management strategies?

Since the electric motor functions as the propulsion motor or generator, it is possible to achieve greater flexibility and performance of the system. It needs more advanced energy management strategies to enhance the energy efficiency of the system.

How does a motor-generator reduce energy loss?

And the new generation of motor-generators reduces system energy loss by switching its magnetic reluctance (analogous in a magnetic circuit to electric resistance in an electrical one) to stop energy leaks while idling and to make power input and output more efficient. But the most important technological development is in the bearing, Jawdat says.
