In the situation that the modular multilevel converter (MMC) needs to maintain a good current control performance within a wide scope of operations such as the intermittent new energy grid connection and electric locomotive, etc, this paper starts from the output current slope generated after the output voltage and system voltage of MMC converter are jointly acted on the equivalent coupling reactance...
With the development of urbanization process and the adjustment of industry structure, the contradiction between increasing power demand and constrained land resources has become more and more serious in metropolis of China. Therefore, the research and development of advanced power transmission technology are of great significance for expansion of urban grid. This paper introduces the low frequency...
In order to achieve the maximum possible polarization lifetime of the alkali atoms in the vapor cell, we discussed several spin-relaxation mechanisms and anti-relaxation methods. We found that octadecyltrichlorosilane (OTS) acts as an anti-relaxation coating for alkali atoms, with good effect in hightemperature conditions.
The turbo-generator units in the vicinity of HVDC transmission system are vulnerable to Sub-Synchronous Torsional Interactions (SSTI). Based on the AC-DC system decoupling transfer function structure of Generator rotation rate to the electric torque, a novel phase correction method of HVDC supplementary subsynchronous multiple models damping controller is proposed, and a SSDC software for adjusting...
