Staff safety is not assured due to the indoor substation’s high environmental risk factor. The Chinese State Grid Corporation has been engaged in intelligentization of substations and employment robots for inspection tasks. autonomous navigation positioning system mobile chassis most important feature this type robot, as it allows robot perceive surrounding environment information at initial position using its own sensors find a suitable path move target point complete task. Automatic basis...
For Electric Vehicles (EV) using on-board charger, the power density and efficiency of its charger are closely related to technical economical restriction overall system. In this paper, an integrated LLC resonant converter center-tapped transformer is proposed improve EV charger. The accurate model considering leakage inductance derived; influences such as change in voltage gain, differences on frequency lost soft switching character which caused by imbalance two secondary windings have been...
The modular multilevel converter (MMC) topology has been widely used in medium/high voltage high-power transmission and distribution motor drive fields. full-bridge submodule (FB-SM) MMC with fault handling capability is currently receiving increasing attention application. However, order to suppress the SM capacitor ripple, usage of capacitors larger capacitance significantly increases hardware cost volume system. In this paper, a modified FB-SM active power decoupling circuit (APD-SM)...
Modular multilevel converter (MMC) is a novel circuit that has appeared in the last few decades, and been extensively applied to medium/high voltage scenarios, especially motor drive owing its scalability easy supply higher number of output levels. As theoretical analysis shows, sub-module (SM) capacitor magnitude positively related current amplitude conversely connected fundamental frequency. Therefore, prime challenge applying MMC variable speed drives there huge oscillation SM during...
Abstract Neutralizing antibodies (NAbs) have attracted attention as tools for achieving PRRSV control and prevention, but viral antigenic variation undermines the abilities of NAbs elicited by attenuated vaccines to confer full protection against heterogeneous field isolates. As demonstrated in this study, monoclonal antibody (mAb) mAb-PN9cx3 exhibited broad-spectrum recognition neutralizing activities PRRSV-1 PRRSV-2 strains vitro. Furthermore, vivo experiments revealed that administration...
Multi-terminal flexible high-voltage-direct-current (HVDC) transmission and DC grid technology are developing rapidly, the hybrid circuit breaker (DCCB) is usually used to protect system, which can quickly remove fault current make sure safe stable work of system. However, existing DCCBs have restrictions regarding one or more following characteristics: economy, fast adaptive reclosing, low on-state losses, no additional pre-charge power source. This paper presents an economical DCCB with...
With the respect of building environmentally friendly city, Inductive Power Transfer (IPT) applied in urban light rail transportation has been regarded as an effective way. There are two main topics IPT power transfer system. The first is to optimize structures track transformer and pick-up achieve high efficiency. second concerned on whether Electro Magnetic Field (EMF) around can meet criterion. In this paper, improved 8-Type contactless proposed. ability which converge internal flux...
Porcine reproductive and respiratory syndrome (PRRS) is one of the most economically devastating infectious diseases in pigs worldwide. The causative agent PRRS virus (PRRSV). In this study, we explored polyethylenimine (PEI), a cationic polymer with different forms (linear or branched), to inhibit replication PRRSV. Our results demonstrate that linear but not 40 kDa branched PEI, 25 were well tolerated cultured cells exhibited broad-spectrum inhibition heterogeneous PRRSV-2 isolates both...
In the context of global ecological degradation and gradual depletion fossil energy sources, importance new power in production development is rising year by year. order to reduce impact fluctuations wind systems on grid due various reasons during connection, this paper proposes an improved Linear Active Disturbance Rejection Control (LADRC) combined with a neural network based grid-side inverter control method, which, analysis characteristics permanent magnet motors current situation their...
Since the DC current has no zero-crossing in high-voltage and large-capacity scenarios, low line impedance results a large growth rate of fault current, breaking requirements circuit breakers (DCCB) are further increased. Hybrid breaker (HCB) represent techniques orientation interruptions HCB can quickly interrupt currents to ensure reliable safe operation grid, which is an indispensable piece equipment flexible systems. Utilizing characteristics thyristor with strong capacity, on-state loss...
The circulating current of modular multilevel converter (MMC) is an inherent phenomenon. existing analysis methods have mainly considered the power losses and submodule (SM) capacitor voltage. Under low-frequency operation, MMC SM has a larger voltage ripple, this paper proposes novel injection method to reduce ripple. based on injecting current, which easily derived by instantaneous information MMC, within phase attenuate lower frequency arm powers. And, it omits using extensive lookup...
Modular Multilevel Converter (MMC) has gained significant traction as a prevalent topology within the realm of variable speed drives. However, during low-frequency operation, voltage fluctuation submodule (SM) capacitors poses challenge, jeopardizing stable operation motor. To overcome this paper suggests an improved control strategy that integrates high-frequency injection approach with decrease in average capacitors. This can effectively reduce ripple at low frequency and mitigate current...
Army soldiers stationed in frigid regions are highly susceptible to foot health problems, partly due the constant sweating and moisture inside closed military boots. Winter boots on market lack attention dehumidification ventilation. To address these issues, we propose a boot system that includes dynamic airflow integrated into core of shoe midsole. This works principle user's heel naturally squeezes airbag under during movement, thus creating an air pressure difference drives movement shoe....
