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 ...
Recently the UK has seen a surge of storms and lightning strikes across the country. With all the bad weather in the UK, we are used to it. 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. You may think that lighting strikes are rare but the UK records between 200,000 ...
As business starts to bounce back, the last thing anyone wants is expensive repairs or maintenance costs. When any electrical equipment breaks down, not only does it cost to fix but it also costs a business in productivity and output – making it a double hit to the pocket. This is where an eco-max surge can provide your business with peace of mind by adding a further layer of protection. ...
The working world has changed as we know it. We are ‘zooming’ more, commuting into the office less and all working from home where we can. This change in working patterns has meant that we are using equipment and technology at home more than ever before. Rather than spending eight hours in the office each day using a business’s power for equipment such as computers, lights, ...
Looking at reducing costs across a business is always front of mind, no matter which industry it operates in, especially now as businesses across the country are looking at ways to get back on their feet. Energy, of course, can be costly and it is the one cost you cannot do without in order to run a business. When looking at making savings to your electricity bill, there are the usual things ...
The plant features 1,100 m² of parabolic reflectors located above ADPO's car park, above a railway line and underneath a high-voltage line, to optimize ground use. Two other CST projects are planned in Ostend and Genk, Belgium. ...
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 ...
Recording Solar Energy: To monitor DC Current/Voltage produced by the solar panel, the PV-3 has one DC voltage input channel (300Vdc), one DC current input channel (+/-100A) and one pyranometer input recording solar irradiation up to 1,500W/m2 (watts per square meter). ...
This paper presents a new evolutionary optimisation algorithm to solve the optimal reactive power dispatch problem with operational constraints using the improved seeker optimisation algorithm (ISOA). ...
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 ...
Placement of shunt capacitors improves voltage profile but unable to serve remote load as it can provide only reactive power. ...
The implementation of cost saving green technology has reduced energy spend across Greater Manchester’s public sector bodies by over £500,000 every year. 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 ...
About Roehampton University Roehampton University is a campus university situated on three major sites at Roehampton in south-west London, in the United Kingdom. The listed buildings stand in grounds close to Richmond Park and Putney, with central London a few miles away. Today the University has a broad range of expertise across the arts and humanities, social sciences and the human and life ...
About Bristol City Council and Fairfield High School Fairfield High School is a specialist performing and virtual arts college under the authority of Bristol City Council. It is designed as a horseshoe shaped building, rising to a maximum height of six storeys, with a central atrium as the school assembly hall. The school provides a high level of insulation with 100 mm thick mineral fibre ...
About the Calderstones Partnership NHS Foundation Trust Calderstones NHS gained its ‘Foundation Trust’ status in 1993, which allows it a larger degree of independence from both the Department of Health and the local NHS Strategic Health Authority than other NHS trusts. It is also classed as a NHS Mental Health Trust, providing specialist care and services for those with learning ...
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 ...
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). Using the proposed switching strategy, the voltage of the inverter capacitors in SMES can be independently controlled. Also, the minimum power and ...
Voltage Optimisation is a key component in any energy efficiency programme and could deliver up to 25% savings on electricity bills. In April the registration period for the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme will start again. Local authorities and companies with a portfolio of private schools will face sizeable fines unless they account for their energy use and make ...
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 ...
