Outdoor Containerized SVG Dynamic Compensation Cabinet
The containerized SVG high-voltage dynamic reactive power compensation system is specifically engineered for outdoor photovoltaic power stations. Given the nature of solar energy generation, these units must be installed in open environments. This raises a critical question: Can equipment requiring continuous power supply withstand prolonged exposure to weather conditions? The answer is affirmative. Utilizing a containerized design with enhanced weather resistance, this specialized SVG cabinet not only resists environmental impacts but also features optimized ventilation channels that ensure efficient heat dissipation. These integrated features enable the SVG system to operate reliably over extended periods, maintaining its service life unaffected by environmental factors for approximately 15-20 years. Below we provide detailed specifications for this containerized SVG system designed for photovoltaic outdoor power stations.

summary :
The ADSVG series comprises three core components: control cabinets, power cabinets, and reactor cabinets. The power cabinet achieves exceptional integration, enabling flexible capacity expansion and enhanced stability. The 35kV equipment features a uniquely designed cabinet structure with modular components that ensure operator safety without requiring safety barriers. The innovative design allows cooling fans to be directly mounted on the cabinet roof, significantly simplifying installation and maintenance processes.
Advantage selling points:
The ADSVG series products with easy operation, high performance and high reliability are designed to meet the urgent needs of users to improve the power factor of transmission and distribution network, manage harmonics and compensate negative sequence current. They have the following features:

2. Fast dynamic response speed, the response time is less than 5ms.
3. Under the premise of sufficient compensation capacity, the total harmonic current distortion rate (THDi) is not greater than 3%.
4. Multiple operation modes to meet the needs of users to the greatest extent. The operation modes include: constant device reactive power mode, constant assessment point
5. Reactive power mode, constant assessment point power factor mode, constant assessment point voltage mode, constant assessment point reactive power mode 2. The target value can be changed in real time.
6. Real-time tracking of load changes, dynamic and continuous smooth compensation of reactive power, improve the power factor of the system, real-time harmonic treatment, compensation of negative sequence current, improve the power supply quality of the grid.
7. Control voltage flicker, improve voltage quality, and stabilize system voltage.
8. ADSVG circuit parameters are carefully designed, with low heat dissipation, high efficiency and low operating cost
9. Compact equipment structure and small footprint.
10. The main circuit adopts the H-bridge power unit chain series structure composed of IGBT, and each phase is composed of multiple identical power units. The output of the whole machine is a step wave superimposed by PWM waveform, which approximates to sine wave. After output reactor filter, the sinusoidal degree is good.
11. ADSVG adopts redundant design and modular design to meet the requirements of high reliability of the system.
12. Power circuit modular design, simple maintenance, good interchangeability.
13. Complete protection functions, such as overvoltage, overcurrent, unit overheating, unbalanced pressure and so on, can realize instantaneous waveform recording of faults, facilitate the determination of fault points, easy to maintain, and high reliability of operation.
14. Featuring a user-friendly interface with RS485 and Ethernet communication interfaces, the system employs the standard Modbus protocol. Beyond providing real-time digital and analog display, historical event logging, process curve recording and query, unit status monitoring, system information inquiry, and process fault detection, it also offers key functionalities including post-power-on self-check, one-touch start/stop control, time-sharing management, oscilloscope (AD channel forced waveform recording), and instantaneous fault voltage/current waveform capture.
15. The ADSVG design contains interfaces for use with FC to achieve an effective combination of fixed and dynamic compensation, providing users with more economical and flexible compensation solutions.
16. No transient impact, no closing surge current, no arc reignition, and no discharge is required to restart.
17. When connected to the system, there is no need to consider the phase sequence of the AC system, and the connection is convenient.
18. It can be installed in parallel and the capacity is easy to expand. The parallel operation uses optical fiber communication, which has fast communication speed and can fully meet the requirements of real-time compensation.

The application of containerized SVG dynamic compensation cabinets is expanding rapidly. With photovoltaic power stations being constructed nationwide in recent years, these systems require stable voltage regulation, active power enhancement, and reactive power reduction. This necessitates SVG dynamic compensation cabinets as the only viable solution, since traditional compensation equipment not only lacks sufficient capacity but also fails to meet response speed requirements. Only high-precision, rapid-response SVG dynamic compensation cabinets can achieve optimal performance. Aodong Electric specializes in manufacturing containerized SVG dynamic compensation cabinets, premium power supply cabinets, and high-quality reactive power compensation systems. As a trusted manufacturer, we welcome inquiries!
