To study the impact of geomagnetic storm on equipment traction electrification system in high-speed railway, geomagnetically induced current (GIC) monitoring devices were installed Hebi East power supply substation Beijing-Hong Kong Dedicated Passenger Line January 2015, and GICs captured during two storms 17 March 23 June 2015. In order to investigate GIC flow path, both track circuit network adopting autotransformer feeding system, a monitor plan was proposed for electrical substation....
At operated voltage, the movement behavior, partial discharge, and harmfulness of linear particle in different positions GIS (high-voltage bus, shield ring, insulator) are still not clear now. In order to study solve this urgent engineering problem, discharge signals, ultrasonic signal, locus particles were recorded observed. The characteristics, metallic analyzed compared. results suggest that: 1) at behavior has a great difference GIS. jumps with small height under high-voltage but jumping...
The power grid is the spine of energy revolution and social progress. With microgrid technology gradually coming into maturity offshore wind continuously developing, development future will be result combination an ultralarge-scale backbone distributed microgrids. Microgrids supplies for families, schools, tourism areas, while large-scale responsible supply industrial large- medium-sized cities, large areas with developed economies.
This paper is concerned with a hyperboloid 3D localization method of the transformer patrol robot based on Empirical Mode Decomposition (EMD) ultrasonic signals and Phase Transform-beta (PHAT-β) generalized cross-correlation. A linear sensor array first employed to receive emitted by robot. The received are decomposed into several intrinsic modal functions (IMFs) different scales EMD. According correlation degree between IMFs signals, large coefficients subsequently selected reconstruct...
Driven by the goal of "carbon neutrality" and "emission peak", effectively controlling system carbon emissions has become significantly important to governments around world. To this end, a novel two-stage low-carbon economic scheduling framework that considers coordinated optimization ladder-type trading integrated demand response (IDR) is proposed in paper for energy (IES), where first stage determines consumption plan users leveraging price-based electrical-heat IDR. In contrast, second...
With the large-scale development and application of offshore wind resources, proportion powered electronic equipment in power systems is increasing, which leads to reduction traditional mechanical inertia system oscillation. To solve above problems, this paper takes grid connected converter an full fan as research object, deduces “inertia” expression physical significance its inner outer loop controller, compares it with motion equation obtain a unified mathematical expression. On basis,...
The DC distribution network system equipped with a large number of power electronic equipment exhibits weak damping characteristics and is prone to low-frequency high-frequency unstable oscillations. current interpretation the oscillation mechanism has not been unified. Firstly, this paper established complete state-space model consisting electric vehicles, characteristic equation derived by establishing model, simplified reduced-order equations describing are obtained. Secondly, based on...
