Reactive currents backstreaming from Solar to Utility Reactive currents backstreaming(from Solar plant) in power supply system is not only harmful but also expensive for financial purposes. Parasite currents in both electricity transmission lines and equipment of solar power-stations cause financial losses because of converting electric energy to thermal (thus making generation amount lower, that ...
Power Quality Power electronics make modern life possible and enable all other areas of innovation. Although stable power delivery seems like a simple problem, the design of a high-efficiency power transmission and conversion system is prone to several problems that reduce efficiency by reducing delivered power. Nonlinear components are needed in power electronics to control the flow of power and ...
Electricity is generated by generating stations and transmitted to load centers from where it is distributed to end consumers. These load centers are controlled by distribution utilities, and there is an inter-change of energy between different utilities connected to the grid. Consumers connected to the distribution utilities, though consuming active energy may or may not consume reactive energy. ...
Night-Time Reactive Power Management and Ferranti Effect Voltage Control in Long Solar PV Feeder Networks Quick Engineering Answer: In large-scale solar PV farms with extensive medium-voltage (MV 33kV/35kV) underground collector networks (often exceeding 50 km in cumulative length), zero-generation night-time conditions trigger the Ferranti Effect. The distributed shunt capacitance of lightly load...

Power factor is a measurement of electrical system efficiency. Many utilities have a power factor penalty built into their rate structure to penalize users with a low power factor reading in their electrical system. To improve the power factor, the most common solution is to install a capacitor banks, But Static Var Generator is the best power factor correction product. There are 3 kinds of...
Static Var Generator (SVG) vs. Traditional Capacitor Banks: The Comprehensive Engineering & ROI Comparison Quick Engineering Answer: While traditional Automatic Power Factor Correction (APFC) capacitor banks rely on electromechanical contactors and discrete capacitor steps to supply static capacitive vars, a modern Static Var Generator (SVG) utilizes high-speed 3-level IGBT inverter technology...
The reactive power consumed by the transformer is generally about 10% to 15% of its rated capacity, and its no-load reactive power is about 1/3 of the full load. Therefore, in order to improve power factor (PF) of the power system, the transformer should not operate at no-load or in a long-term low-load operation state. Vigorously improving the power factor of transformers, reducing line losses, a...
