Hydraulic pumps play a crucial role in various industries, enabling the conversion of mechanical energy into hydraulic energy to power equipment for tasks such as lifting, pushing, and moving heavy loads. From construction sites to mining operations, these pumps are indispensable for ensuring efficiency and productivity. However, certain applications, especially those in remote or off-grid ...
The power quality monitoring application dQuality from Dlaboratory Sweden AB (publ) has turned out to be not only an efficient solution monitoring reactive power from wind production, or keeping track of harmonic distortions, but a useful tool for grid planning and investment. Monitoring power quality has thus turned out to be essential in creating a sustainable and reliable power grid. In the ...
The reactive power quadrants in electric meter refer to dividing a plane coordinate system into four regions, with the horizontal axis representing reactive power and the vertical axis representing active power. Each region represents a different combination of reactive power and active power states. These four regions are known as quadrants I, II, III, and IV, each with its own meaning and ...
The demand of an electricity meter refers to the maximum average value of the electrical load within a certain time interval. In the power industry, it is common to use a 15-minute interval for measurement and calculation. The maximum average value within this time interval is the demand of the electricity meter, and there are two common calculation methods: interval-based and sliding-scale. The ...
Traditional energy meters are mainly used for energy measurement, while smart energy meters enhance this function by adding communication, data processing, prediction analysis, and self diagnosis. By real-time monitoring and analyzing the operating status of equipment, smart energy meters can self diagnosis and provide warnings to power companies, enabling them to take proactive measures to ...
An electric energy meter is an instrument used to measure electrical energy, which is also known as a kilowatt-hour meter or electricity meter. Its unit of measurement is the degree or kilowatt-hour. It is a product of power and time and can be used to measure the power consumption of end users, serving as the basis for billing by electric companies. Electricity is an indispensable energy source ...
Tariff power meter divides the day into different electricity price periods and records energy consumption. It encourages rational electricity use and peak load shifting to optimize energy allocation and stabilize power systems. It can change consumers' electricity habits by displaying daily power consumption and cost savings. Supporting systems and education are necessary for effective ...

Combined with ...
Smart grids have been in the headlines for over a decade. Today we’ve finally reached an impasse: our existing energy infrastructure is no longer fit for purpose. It is crumbling under the weight of abnormal weather conditions, demand fluctuations, and momentous changes to baseloads, historically supported by fossil fuels. Just a few short months ago, flash flooding across Europe left many ...
Clarke Energy supplies Nova Power & Gases’ gas-fuelled peaking station with four INNIO Jenbacher J620 gas engines. The project will improve efficiency and stability of power to the Reif Industrial Park. Construction is ongoing at power plant located in Campia Turzii, Cluj County. Bucharest, Romania - April 2021 - Construction is progressing in Campia Turzi, where Clarke Energy ...
Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...
A modern maximum power point tracking (MPPT) method based on the incremental conductance (IncCond) control algorithm is discussed. This method features a variable step iteration of duty ratio to get over the trade–off between dynamic performance and steady state oscillation around maximum power point (MPP). Moreover, in the aim to get an excellent precision and a swift response independently of ...
This paper describes a new approach to generation expansion planning (GEP) problem to optimise simultaneously multiple objectives such as cost and stability margin. It is formulated as a combinational optimisation problem in order to determine the type and capacity of the new generations as well as their timing and placement. This study presents a comprehensive model of hierarchical optimisation ...
In this paper, particle swarm optimisation (PSO) is used to optimise the PI controller parameters of the d.c. link voltage controller of a 48 pulse static synchronous series compensator (SSSC). The optimised controller improves the torsional performance of the SSSC compensated power system. High gain of power system stabilisers (PSS) can adversely affect the torsional performance of an SSSC ...
The impact of the wind generation on the power systems is no longer negligible if high penetration levels are going to be achieved. It is very important to boost the transfer capability of the transmission system while improving the utilisation of transmission assets to accommodate high penetration of wind power on the network. Hence, more sophisticated control schemes using advanced power ...
Why is an activation procedure or break-in necessary for a membrane electrode assembly (MEA)? A large reason for performing an activation procedure or break-in is to properly humidify the membrane portion of the MEA that was dried out during the hot press stage of the membrane electrode assembly(MEA) production. MEAs will not work well when they are not fully humidified (see article: Why is ...
A 360 W photovoltaic (PV) module power with a maximum power point tracking (MPPT) algorithm is analysed and presented. In this study, the control algorithm is improved and then applied to the PV system. The results obtained show the ability of this algorithm to control high powers when weather conditions are changing. Under the same conditions, this improved technique offers, in steady state ...
In power system, the application of the power system stabiliser (PSS) has been proved to overcome the stability of power system. It is necessary to determine the appropriate PSS parameters. In this paper, a new cost function is presented for the tuning of PSS parameters. Optimisation of PSS parameters has been done by particle swarm optimisation algorithm. The power plant system that is simulated ...
We distort reality when we omit the health and environmental costs associated with burning fossil fuels from their prices. When governments actually subsidize their use, they take the distortion even further. Worldwide, direct fossil fuel subsidies added up to roughly $500 billion in 2010. Of this, supports on the production side totaled some $100 billion. Supports for consumption exceeded $400 ...
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 ...
