Wenzhou Oujian Resource Utilization Technology Co., Ltd. Technical Transformation Project

Wenzhou Oujian Resource Utilization Technology Co., Ltd., located in Ouhai District, Wenzhou, is an environmental protection technology company under Wenzhou Construction Group. The company focuses on the resource utilization of construction waste, transforming construction waste into high-quality recycled building materials through advanced technology, promoting green circular development, and helping to achieve carbon neutrality goals.

Background

1. Capacity decay of original compensation equipment: As time goes by, the original reactive compensation equipment (such as capacitor banks) may have reduced compensation capacity due to aging, wear and other factors, and cannot meet the needs of the current power grid.

2. Impact of nighttime shutdown: During the nighttime shutdown, the transformer is in a no-load state, while auxiliary power such as lighting still needs to be supplied. This causes the original compensation equipment to be unable to work effectively under light load or no-load conditions, and may even generate reverse reactive power, further reducing the power factor.

3. Power factor does not meet the standard: The above factors work together to make the company's overall power factor lower than the standard set by the power department, which will not only increase electricity bills, but may also affect the stability and security of the power grid.

Faced with increasingly severe challenges in power grid quality, the company decided to transform the compensation cabinet in the power distribution room to improve the overall quality and operating efficiency of the power grid. After in-depth research and comparative analysis, the company decided to use Zhejiang Yide YDK-SVG static VAR generator, YDX series anti-harmonic intelligent capacitor and other power quality products.

Product Introduction:

YDX series anti-harmonic intelligent capacitors are a new generation of reactive power compensation equipment that is efficient and energy-saving, filters harmonics, and improves power factor. They replace traditional reactive power compensation equipment consisting of intelligent reactive power compensation controllers, fuses, switching switches, filter reactors, power capacitors and other loose parts.

YDK-SVG static reactive generator is a new type of power electronic device used for dynamic reactive compensation and three-phase imbalance control. It can analyze the reactive content of load current by sampling load current, and then control and actively output the corresponding reverse reactive current, and respond quickly to compensate for the reactive component in the load current to achieve dynamic tracking compensation.

The transformed power grid system not only successfully solved the problems of insufficient reactive power compensation caused by capacity attenuation of the original compensation equipment and nighttime shutdown, but also significantly improved the overall quality and operation efficiency of the power grid. The power factor has been effectively improved, and the electricity bill expenditure has been effectively controlled. At the same time, the stability and security of the power grid have also been significantly enhanced, providing a strong guarantee for the company's production and operation.
