With the development of high voltage long distance transmission and expansion of the grid, the reactive power compensation device with excellent adjustment function becomes more and more important. This paper aims to study a high temperature superconducting magnetically controlled saturable reactor (HTS MCSR), which has a wide range of stepless reactive power capacity adjustment and little operating loss. An adjustable reactor topology of three split limbs core was proposed. Based on research of structure and theory, the operating characteristic was obtained. A normal conductive prototype was manufactured. Simulation and test were done to verify the adjustment characteristic of this reactor. The results confirm the concept and provide an experimental basis for developing HTS MCSR in the future.

There are many problems for traditional reactive power compensation devices to be applied in the grid, such as discontinuous adjustment, small capacity, complex control and harmonics. This paper aims to study a high temperature superconducting magnetically controlled saturable reactor (HTS MCSR), which has a wide range of stepless adjustment. It has a good application prospect in large scale reactive power compensation devices. Based on research of theory and core structure, a shaped-cylinder core is proposed. By means of calculation of saturable reactor and analysis of algebraic and magnetic circuit model, design of 220V HTS MCSR is finished. Results of normal conductive reactor prototype and simulations verify that the range of inductance adjustment is very wide. Furthermore, conceptual design of 35kV HTS MCSR confirms its reactive power capacity is so large, therefore, it is suitable for high voltage power system.

With the development of high voltage long distance transmission and expansion of the grid, continuous reactive power compensation devices, such as controllable reactor, become more and more important. This paper describes the design and prototype test of a high leakage reactance transformer-based high temperature superconducting controllable reactor (HLRT-HTSCR). Characteristics test results show the excellent impedance regulation characteristic of the prototype. DC critical current test of the superconducting winding shows that attention should be paid to the critical current of superconducting coil, avoiding over-current condition. This paper reveals the characteristics of HLRT-HTSCR by experiment, and will be of important practical significance to promote its development.

Traction Power

The article presents a method for selecting the parameters of the current-voltage characteristics of adjustable reactive power compensation devices used at sectioning stations of railway sections electrified by alternating current with a voltage of 27.5 kV. This technique is based on the experience of operating two types of devices in the traction power supply system. Power control of these devices is implemented by the voltage level at the switching point. Selection of the setpoint voltage and slope characteristics was done. The developed method allows increasing the efficiency of devices by eliminating the voltage losses on the active component of traction loads. That will reduce the loss of electricity in the system of traction power supply. Changing the parameters of the characteristics will increase the relationship between the reactive power consumed in the zone and the voltage measured by the devices. Following the results of the formation of the methodology, an example of the choice of characteristics for a real compensation device is presented.
