As a new type of green energy technology, organic solar cells (OPVs), the core of which is to use photoelectric conversion organic materials to convert light energy into electrical energy, have the advantages of all-solid-state, low cost, low temperature fabrication and large-area flexible devices. The photocurrent flow of OPV depends not only on photogenerated carriers but also on the interface ...
The choice of the cross-sectional area of the power cable is related to the investment, the loss and voltage quality of the line, and the service life of the cable. If the cross-sectional area of the power cable is too small, the voltage quality will drop, the line loss will be too large, and the initial investment will be too high. Therefore, the appropriate cross-sectional area should be ...
But if you run a business that is reliant on a lot of electrical equipment, a lightning strike or a power surge can damage it and lead to it underperforming or in need of repair. ...
All electrical equipment is prone to power surges, such as an uneven or sudden distribution from the grid, and lightning strikes, even if they take place miles away from your place of work. And there are more lightning strikes than you may think, as each year the UK and Ireland typically experience over 200,000 to 300,000 lightning strikes. All these types of ...
An over-supply of power can shorten the life of the equipment. It basically burns it out quicker than it ought to. So, what’s the solution? A voltage optimiser. Our eco-max voltage optimiser will regulate the power coming into your home and lower the voltage to provide ...
But we don’t need all that power as lots of equipment can work efficiently at 220 volts. Basically, any power suppled over this voltage is wasting energy which you are needlessly paying for. ...
Egypt advances plan for five new CSP plants The Egyptian government and Cairo-based Smart Engineering Solutions are moving ahead with a plan to build five CSP plants for a total capacity of 250 MW, Egyptian media reported earlier this month. Smart Engineering Solutions plans to select the preferred technology supplier from a shortlist of 16 companies by the end of November, Osama Kamal, the ...
Motor; 460kW Leroy Somer Permanent Magnet Compressor Motor. 400V, 3600rpm. Initially overhauled in May 2017, when 2 x Insulated Bearings were replaced, Excessive Bearing Failure was once again detected in November 2017. It was agreed to complete a Shaft Voltage Test, as the motor is powered by VSD, Shaft Voltage of 54V Peak to Peak was detected. Upon inspection of the power cable between ...
Accsense Electrocorder Kit for Solar Energy Audit As summer begins, photovoltaic, PV, panel installers and servicepersons can realize significant benefit from using solar energy monitoring to prove to clients that the promised savings are really delivered. Alternatively, if you’re the owner of one of these systems and you need to prove reduced draw from the grid to qualify for grants or for ...
Optimal reactive power dispatch (ORPD) is one of the important non–linear mixed–variable optimisation problems in power system which includes both continuous and discrete control variables satisfying both equality and inequality constraints. This paper presents a new evolutionary optimisation algorithm to solve the optimal ...
This paper presents a single–stage isolated power factor corrected power supply (SSIPP) fed permanent magnet brushless DC (BLDC) motor drive. An advantage of fast voltage regulation with single voltage control loop of SSIPP is utilised to develop a power factor correction (PFC) based BLDC motor drive. The speed of BLDC motor is controlled by varying the DC link voltage of the voltage source ...
In the last few years, a number of factors have led to an increased interest in distributed generation (DG) scheme because placement of DG is the most effective method in reducing the power loss of the distribution networks to serve remote loads. Placement of shunt capacitors improves voltage profile but unable to serve remote load as it can provide only reactive power. So, combination of both ...
Getting the source right powerPerfector is the world’s only Voltage Power Optimiser, giving energy, carbon and cost savings by efficiently optimising a site’s supply voltage. By optimising the voltage, electrical equipment runs more efficiently and consumes less ...
Using Official Journal of the European Union (OJEU) approved procurement and by implementing cross organisational communication, AGMA has been able to adopt Voltage Power Optimisaton across 90 sites. By becoming early adopters of VPO technology, many have been able to get ahead of the game in reducing their energy costs and carbon emissions. ...

PV system arrays generate DC current. The solar modules are wired in series, and the system voltage is the sum of the maximum output voltage of all of the modules in a string. 600 Vdc maximum was chosen as an optimal system voltage to reduce installation costs by reducing conductor size and to stay below the 600V threshold in NEC Article 490. Prior to the growth in the number of installed PV ...
This paper presents a novel and optimised switching strategy and control approach for a three-level two-quadrant chopper in a three-level neutral point clamped (NPC) voltage source inverter (VSI) superconducting magnetic energy storage (SMES). ...
Not only valuable energy, cost and carbon savings, Voltage Optimisation provides power quality improvements too The voltage supplied to the majority of sites is above the level it needs to be. ...
Among several energy saving initiatives, Variable Speed Drives can help manufacturing to achieve 60% of immediate energy saving, reports Envido. Recently there has been an influx of regulations applied to manufacturing industry that has a major impact on energy use. Among them the CRC Energy Efficiency Scheme will apply mandatory emissions trading to cut carbon emissions from large non-intensive ...
