The power quality monitoring and management solution provides users with customized power quality consulting, monitoring, analysis, and management, offering comprehensive technical support and integrated power quality solutions. By detecting the power quality data on-site and simulating analysis based on the harmonic network flow and dynamic voltage distribution of the distribution network, the compensation model is continuously adjusted to ultimately customize the most economical and effective power quality solution for users, addressing issues such as reactive power, harmonics, and voltage sags. This improves power quality for users, reduces equipment damage, and provides intuitive and accurate measurement and control methods for users' contract energy management, technical energy saving, and management energy saving. The full process service for monitoring, analyzing, and managing power quality in the distribution system is implemented mainly in the following five steps.
The power quality management device achieves monitoring, analysis recording, and control of power quality in the user's distribution system. The device is flexible, capable of being configured in a layered, distributed model "object-oriented" or using a "function-oriented" monitoring, analysis, and control method to form a power quality management system. The regional power quality and energy consumption control system collects power quality and energy consumption data from the user side in real-time through wired or wireless (3G) networks, automatically completing power quality assessment based on the system model, allowing managers to promptly identify and effectively address issues, achieving closed-loop management and enhancing the regional power quality management level.
It can be widely applied in power systems as well as in industries such as metallurgy and steel, coal mining, electrified railways, wind power generation, and building distribution for power quality monitoring and management.
lComprehensive service for power quality solutions - power quality monitoring and analysis, governance scheme design, installation and use of governance devices, governance effect evaluation, and comprehensive power quality management system, providing users with convenient, reliable, and high-quality power quality governance services.
lThe system adopts a distributed B/S intelligent architecture, monitoring, analyzing, evaluating, alarming, and assisting decision-making in real-time for users' electricity consumption and power quality conditions, promptly identifying and addressing various power quality issues.
lThe power quality governance products are comprehensive, with a rich variety of products for harmonic, reactive power, and voltage sag governance, meeting various power quality governance needs on user engineering sites.
lAll power quality governance products adopt a modular structure. The 30A and 50A small capacity products are fully modular, while the 100A and 200A large capacity products have modular functional units, allowing for quick assembly, debugging, and maintenance.
lThe active harmonic reactive power compensation device uses a current control method based on instantaneous reactive power theory, fast FFT, and fuzzy control, achieving a compensation accuracy of up to 95% and a response speed of as fast as 300us, with excellent performance in harmonic and reactive power compensation products.
