This article focuses on the high-frequency resonance and harmonic elimination in electrified railway transportation system. The high-order currents, which are generated by grid-side converter locomotives' drive system, will inject into traction power supply system (TPSS). These injected currents harmful to electrical equipment along transmission line TPSS, causing vibration, overheating, increased losses of transformer, deteriorating quality TPSS. Even worse, these harmonics can be amplified...
In the context of energy transition and low-carbon electricity, a economic dispatching model integrated system (IES) is built, which considers power-to-gas (P2G) carbon trading mechanism to improve efficiency minimize emissions. Firstly, operating characteristic P2G analyzed, an interval-adaptive ladder-type considering emission reduction benefit proposed. Then, proposed introduced into system, IES taking account uncertainty renewable output constructed. Finally, The numerical case study...
There is ever-increasing high-order harmonic pollution caused by high-speed locomotives with PWM rectifier in nowadays railway traction power supply system (TPSS). These components injected from the electric train will aggravate transformer vibration, noise, and loss interfere other powered same power-supply station. Harmonic resonance occur when frequency matches inherent of TPSS. An inductive filtering-based designed for restricted installation space this paper, aiming to eliminate...
The air-core reactor has the advantage of good linearity and low noise, however problem large space occupation. Power filter with is indispensable widespread use power electronic devices in electrified transportation system urban distribution system. It hoped that can be integrated transformer to reduce while performance kept. In this paper, a non-orthogonal decoupling (NOD) method proposed, as well new design integrate linear based on it. Further research including structure (ILR) windings,...
Under the dual pressure of energy and environmental crisis, planning a regional integrated system (RIES) is more practical significance. This paper proposes capacity method that can be applied to electricity-cold-heat-gas coupling achieve optimal configuration RIES. The RIES studied in this includes distributed renewable energy, multiple storage devices, equipment such as combined heat power (CHP) pumps. It not only meets demand cold, heat, electricity load but also improves economic...
Multisystem locomotive can operate in two or more different traction power supply systems (TPSS). At present, for multisystem locomotives, the existing topology under DC situation may either sacrifice stability of DC-link voltage, complicate designed structure line-side converter. This paper proposes a converter based on multiplexing transformer windings to achieve voltage matching. The proposed has advantage simple structure. Compared with traditional AC-powered locomotive, this only adds...
