Problems encountered in the laying of underground cables
Problems encountered in the laying of underground cables Attention shall be paid to the cable trench laying of underground cables. Cables with different voltage levels shall be set with different supports, and the cable trench itself shall pay attention to drainage measures. And consider measures to prevent small animals such as rats from entering. Question 1 Can high and low voltage cables be ...

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 ...

The Path to a Vehicle-to-Grid Future
Is a vehicle-to-grid future possible, where bidirectional chargers allow electricity to flow from electric vehicles back to the grid during peak demand? Given the current state of electric vehicle (EV) technology, coupled with existing pilot projects, we believe it’s more suitable to ask: what useful vehicle-to-grid applications can we implement today, and what valuable benefits await to be ...

Electrodeionization (EDI) using Voltage Control
In electrodeionization, DC voltage is the force for driving ions out of the stream to be purified. Current is a result of the movement of ions. Both as a matter of physics and as a practical matter, SnowPure recommends using “Voltage Control” for EDI: set the DC voltage potential to the EDI system and walk away–let the current follow the ion load on the EDI. The physics say ...

Nonlinear phenomena in DC–DC buck converter by means of iteration mapping technique
In this paper, the nonlinear phenomenon in DC/DC buck converter is studied. A practical design for a DC/DC buck converter was considered in this study, which results in a more comprehensive understanding for the phenomenon. The nonlinearity of the buck converter is studied using the iteration mapping technique. The results showed that if the system has a well–designed buck converter as well as a ...

Power quality problem mitigation by unified power quality conditioner: an adaptive hysteresis control technique
An adaptive hysteresis current and voltage control technique for controlling Unified Power Quality Conditioner (UPQC) is proposed in this paper. The novelty of the proposed method is the series and shunt active power filters (APF) present in the UPQC has been controlled by the separate adaptive controllers for reducing the voltage and current perturbations. Here, the adaptive control technique ...

Designing renewable contracts that value CSP storage
As California ramps up its storage requirements, it has not included Concentrated Solar Power (CSP) with integrated energy storage. Instead it is testing pilot projects using batteries at utility-scale, even though it must be obvious to bean counters at utilities that batteries are never going to compete with utility scale CSP storage. By Susan Kraemer The 32 MWh battery storage pilot for ...

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 ...

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 ...

Adaptive hysteresis-band current controller
One of the most complicated control problems in variable speed AC drives is the difficulty of processing feedback signal of the outer loop in the presence of harmonics. However, conventional fixed band hysteresis controller has a variable switching frequency throughout the fundamental period. A variable-hysteresis-band controller comes as a solution to reach an optimal ripple current. An ...
