History and Development of Power Quality Products: From Traditional to Intelligent
The evolution of power quality products mirrors the dynamic interplay between the evolving needs of power systems and advancements in technology, showcasing human ingenuity and creativity. As power quality products and power systems have co-evolved, they have collectively contributed to creating a more reliable and efficient power environment for society. This development trajectory underscores the ongoing adaptation to changing power system demands and the relentless march of technological progress.
The cycle and process of power quality product evolution
Traditional stage (early to mid-20th century): Main representative products: passive filters, capacitors, reactors, etc. Features: simple structure, low cost, high reliability, but single function, can only solve specific power quality problems, such as reactive power compensation and harmonic suppression. It has great limitations, cannot dynamically adapt to system changes, and is difficult to deal with complex power quality problems.
Power electronics stage (mid-20th century to late 20th century): Main representative products: active power filter (APF), static VAR compensator (SVC), dynamic voltage regulator (DVR), etc. Features: using power electronics technology, with fast response and dynamic compensation capabilities, can effectively solve problems such as harmonics, reactive power, voltage fluctuations.
Intelligent stage (early 21st century to present): Main products: intelligent power quality conditioner (IPQC), unified power quality conditioner (UPQC), power quality monitoring and management system, etc. They integrate advanced sensing, communication and control technologies, have real-time monitoring, analysis, diagnosis and governance capabilities, and can achieve intelligent management and optimization of power quality.
Driving factors for the development of power quality products:
Complexity of power systems: The access of new energy, distributed generation, electric vehicles, etc. to the power grid brings new power quality problems.
Increased user demand: Precision equipment has increasingly stringent requirements for power quality.
Technological progress: Power electronics, information technology, artificial intelligence, etc. provide support for the innovation of power quality products.
With the development of energy Internet, power quality products will be more intelligent, networked and customized, providing guarantees for building a safe, reliable and efficient power system.
Power quality product development process:
From traditional passive filters to active power filters (APF): APF can dynamically compensate for harmonics, overcoming the limitation that passive filters can only target specific frequencies.
From static VAR compensator (SVC) → static synchronous compensator (STATCOM): STATCOM has faster response speed, better compensation effect and smaller footprint.
In short, the development history of power quality products reflects the continuous changes in power system needs and the continuous advancement of technology. In the future, power quality products will be more intelligent, networked and customized, providing guarantee for building a safe, reliable and efficient power system.
