why do power meter need anti-temper function?
ith the increasing demand of users for electric energy, some users take various methods of stealing electricity in order to obtain electric energy free of charge. Not only does it causes a large amount of loss of electrical energy and a great economic loss to the power supply organization, but also disrupts the normal power supply order and poses a safety hazard to the power users. There are many ...

Power Quality: Top Protection
The Power Quality problems of an electrical distribution network are often generated locally within the structures and can depend on various situations, such as, for example, construction works, switching on high loads, faulty distribution components and particular basic electrical disturbances. Furthermore, external causes such as atmospheric events (hurricanes, lightning, snow, ice and ...

How to prolong the life of your electrical equipment now more of us are working from home
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, ...

What are the PMG and AREP Systems for?
To ensure the generator’s stable operation, it is important that there are no major voltage fluctuations. For this purpose, an excitation current is created to provide power to the AVR (Automatic Voltage Regulator), a device that maintains the generator's nominal voltage at a preset value, even when there are sudden load variations or in the case of special operations, such as: parallel ...

Interoperability Profiles – A Better Way to Buy Grid Technology
Imagine browsing online for a new computer app. Once you have located the app, you swiftly hit the ‘download’ button – and immediately realize you’ve purchased the Windows version, which is incompatible with your Apple device. You have become a victim of technology tribalism. If your device represents a utility’s service territory, and the app represents new ...

Managing Battery Charging - Using Diversion Loads
Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. Often, diversion control is the solution. Off-grid "hybrid" combinations of solar, wind, or microhydro have been around for decades. These renewable ...

Beyond the Tesla Powerwall: How energy storage is shaping up in Ontario - How energy storage changes everything
There are not many entrepreneurs who can command a room like Elon Musk. When he stepped onto a stage in May to unveil the Powerwall the audience oohed and ahhed and dutifully pre-ordered more than 38,000 of Tesla’s new home battery systems. And while Tesla gets the headlines other energy storage players shouldn’t be jealous. Musk just gave the nascent industry a billion dollars worth ...

Multi–objective DG planning for reliability, efficiency, and power quality including voltage rise issue
The reliability of service is very important for sensitive loads. This is only possible when additional generators such as distributed generators are available on strategic load centres to feed these sensitive loads in case of emergency. This paper presents a method to optimally allocate the distributed generations in terms of site and size to satisfy each objectives of multi–objective ...

An improved power quality boost–flyback SSIPP fed BLDC motor drive
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 ...

STATCOM–based voltage and frequency regulator for stand–alone asynchronous generator
This paper presents a STATCOM–based voltage and frequency regulation for stand–alone asynchronous generator feeding linear and nonlinear loads. The SEIG have inherent poor voltage and frequency regulation. The voltage and frequency depend upon the load current and power factor of the load with fixed excitation capacitor employing unregulated turbines. The changing consumer load requires variable ...
