FGI Test SVG, the superior choice for power testing
In the process of continuous development and upgrading of the power system, accurate and reliable test equipment is crucial to ensure the stable operation of the power grid and the development and testing of new equipment. The experimental SVG equipment created by FGI Science And Technology Co., Ltd. and its partners has become the core support of flexible AC transmission (FACTS) medium and high voltage product test system with its excellent performance and professional quality.
1.Accurately adapt to various test requirements
The SVG equipment used in this test covers two models of 10kV companion SVG (20Mvar three-phase) and 27.5kV companion SVG (10Mvar single-phase), which fully meet the test scenarios of different voltage levels and capacities.
10kV test SVG can automatically run in 3kV, 6kV and 10kV busbars, and the reactive power capacity adjustment range under each voltage is accurate and continuous, such as ±20Mvar at 10kV, ±10Mvar at 6kV, and ±5Mvar at 3kV, providing accurate reactive power compensation for the simulation of complex power grid conditions.
The 27.5kV SVG also achieves continuous adjustment of ±10Mvar at its rated voltage to ensure stable and reliable reactive power support for the high voltage test.
2.Core performance advantages are evident
(1)High efficiency and low harmonics
The average loss is less than 0.8%, significantly reducing operating costs and improving energy efficiency; The harmonic characteristics are less than 3%IN, effectively reducing the harmonic pollution of the power grid, ensuring the purity of power quality, and laying the foundation for high-precision test data collection.
(2)Fast response ensures test accuracy
Step response time and transient voltage drop response time strictly follow the NB/ T42043-2014 standard, quickly and dynamically adjust reactive power output, accurately simulate the transient changes of the power grid, capture the performance of power equipment under complex conditions, and ensure that the test results truly reflect the actual operation capacity of the equipment.
(3)Stable operation to cope with complex power grids
The sustainable operating voltage range is 0.75-1.3p.u., stable operation when the system voltage imbalance is less than 60%, ADAPTS to the normal voltage fluctuation and imbalance of the power grid, provides a solid guarantee for long-term, multi-condition test, and ensures that the test process is not interrupted by power grid interference.
3.Diversified operation mode innovation experience
(1)Automatic compensation intelligent optimization
Reactive power automatic compensation mode Focus laboratory power access point reactive power and power factor, real-time dynamic adjustment, fusion filtering and unbalanced current compensation, maintain power quality up to the national standard. The voltage control mode accurately stabilizes the access point voltage, and the target voltage is flexibly set, which fully meets the strict requirements of different tests on voltage, reactive power and harmonics, and improves the intelligent level of the test system.
(2)Precise customization occurs manually
Manual reactive power generation can specify reactive power according to the precise output of the test design; Manual harmonic generation can produce single or combined harmonics, the output capacity meets the needs of multi-voltage levels and capacity tests, such as 10kV (20Mvar), 6kV (10Mvar), 3kV (5Mvar), 27.5kV (10Mvar) harmonic currents accurately reach the standard, and has 1.05 times long-term overload capacity. Create conditions for the study of harmonic characteristics. Manual unbalanced current generation for star and triangle connection test, output specific unbalanced current, with minimal deviation, to help power equipment testing and analysis under unbalanced conditions.
4. Intelligent control protection system escort
(1)Advanced control system integration and collaboration
Control panel cabinet design strong anti-interference, using imported optical fiber and well-known brand accessories. The local human-machine interface, the main controller and the pulse distribution unit work together to realize the remote/local flexible monitoring of the operation mode and parameters. The parameters are not lost after 5 years of power failure. The Ethernet communication ensures high-speed and stable data transmission, supports remote operation and monitoring, and brings convenient and efficient experience for the test operation.
(2)Comprehensive protection strategy reliable guarantee
Complete protection function covers busbar, device, device, communication, temperature, water flow and other aspects, such as busbar overvoltage, undervoltage, device overload, power device damage protection. Protection configuration table detail specification protection set value, logic, rapid response to failure, to ensure equipment and test safety, reduce the risk of equipment damage, reduce the loss of test interruption.
5.Professional services all the way worry-free
(1)Efficient collaboration in project management
The senior project manager coordinates the project, from design and manufacturing to installation and commissioning, acceptance and delivery, closely communicates and coordinates with all parties to ensure the efficient promotion of the project, ensure the accurate connection of each link and the timely completion, and save time and cost for customers.
(2)Technical documentation is detailed and complete
