Abstract:

HTS Superconducting superconducting magnetic energy storage (SMES) can be utilized to ensure stable operation and high high-quality power supply in power systems. The lumped parameter network model of the magnet, which is taken example by transformer transient model, composed of self-inductances, mutual couplings, and series and shunt capacitances,is typically used to analyze the voltage distribution on the HTS magnet. The model is helpful in regards to the insulation design of SMES magnets, so its accuracy is a crucial consideration. This paper introduces an HTS SMES lumped parameter network model and corresponding parameter calculation technique. Tests were run on under various conditions and the results were compared against the simulation results to verify the model's accuracy. Suggestions for insulation design and transient suppression are presented based on our observations.

I. Introduction

Smes systems can store energy in superconducting magnets and are commonly utilized for a variety of power system applications [1], [2]. Generally, a HTS SMES system consists of a HTS magnet, cryogenic system, power conditioning system (PCS), and monitor and control system (MCS). Fig. 1 shows the basic topology of a typical SMES system with a HTS magnet connected to a voltage source converter (VSC) via a DC-DC chopper [3]. During the power exchange process, the voltage across the HTS magnet is produced via switching operations of the PCS semiconductor devices and is characterized by steep rising edge and high frequency. Per the high frequency transient model, PWM voltage is not distributed evenly between windings. This transient overvoltage can endanger the insulation and even lead to SMES operation failure. To this effect, understanding the electromagnetic transient interaction between the HTS magnet and the PCS is critical in regards to the successful design of SMES magnet insulations. This type of research can also provide a basis from which to investigate transient suppression methods.
