What is Solar Water Pumps?

Aug , 31 2021

Solar water pumps are a relatively new concept in mechanics. Through solar panels, the pump can eliminate the cost of energy and provide a more feasible option that uses energy from the sun (and not fuel-burning mechanisms) for pumping water. Therefore, a large quantity of energy is being released right at the time when it is needed the most. Components: The main components in a solar pumping syst...

Integration of ESS with Renewable DC Micro grids

Sep , 01 2021

Renewable energy based micro grids are emerging as a viable solution for isolated rural areas or oceanic islands. The main issue which plagues its development is the variable/intermittent nature of renewable sources, which makes it tough to achieve smooth operation. Such fluctuation may lead to load imbalance, instability, and damage to system components under the influence of varying loads. In su...

DC-DC Converters-A suitable alternative to battery chargers

May , 09 2022

What if you had all the power you wanted or needed at 125 Vdc, but your site manager suddenly handed you a requirement for 24 Vdc to run some communication gear? You might tell him to buy a 24 V battery and a 24 V battery charger. But, these elements come with costs: initial, maintenance, and probable future battery replacement. There is another way: for approximately the same cost as the battery ...

Efficiency of DC power system

Jun , 27 2022

In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

Power Factor and Harmonic Analysis in Single phase AC to DC converter

Aug , 15 2022

Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part ofmost of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC toDC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is used ...

Inverter common fault contents and solutions

May , 11 2024

As an important component of the entire power plant, inverters can detect almost all power plant parameters for both DC components and grid connected equipment. If there is an abnormality, the health status of the supporting equipment in the power station can be checked through the feedback information from the inverter. Below are some common fault information and handling methods for photovoltaic...
