Gaoyou Changtong New Building Materials Co., Ltd. Technical Transformation Project

Gaoyou Changtong New Building Materials Co., Ltd., as an important local building materials manufacturer, decided to renovate its concrete mixing station to improve production efficiency and power quality.

After investigation by our technical staff, it was found that after the photovoltaic grid connection, the control logic of the on-site reactive power compensation controller was chaotic and reactive power compensation could not be performed effectively. The grid connection point was moved from the load end to the incoming line cabinet, but there was still a situation of power adjustment of electricity charges, which could not meet the requirements of power factor compliance.

One of the key points of the transformation is to introduce the YDK-SVG static VAR generator to enhance the stability of the power grid and improve the power quality. At the same time, combined with Yide Cloud, real-time power data monitoring and recording can be achieved to ensure the effective operation of the entire system.

Product Introduction:

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 YDK-SVG static VAR generator plays a vital role in the renovation project: it not only significantly improves the power factor, but also stabilizes the grid voltage, increases transmission capacity and improves power quality.

Application of Yideyuntong:

As the core device of data communication, Yideyuntong realizes the following functions:

Real-time alarm for abnormal situations: Yide Yuntong has a real-time alarm function, which can trigger an alarm immediately when any power abnormality is detected, and quickly notify the operation and maintenance personnel through various means to ensure that the abnormality is handled in a timely manner.

In terms of protecting power quality: adopt advanced power quality protection technology, through intelligent analysis of power grid data, real-time monitoring and adjustment of voltage and current waveforms, effectively suppress harmonics and flicker, and ensure that the power quality provided by the power grid is stable and reliable.

Real-time monitoring of power data: Yide Yuntong integrates a high-precision data acquisition module, which can monitor various power data in the power grid in real time and accurately, including voltage, current, active power, reactive power, etc., providing operation and maintenance personnel with comprehensive and detailed power grid operation status information.

Power factor data monitoring: Yide Yuntong pays special attention to the real-time monitoring and optimization of power factor. It analyzes power factor data through intelligent algorithms and automatically adjusts reactive power compensation devices to ensure that the power factor of the power system always remains within a reasonable range, thereby improving energy efficiency and reducing losses.

Gaoyou Changtong New Building Materials Co., Ltd.'s technical transformation project has achieved the improvement of grid stability and power quality by introducing YDK-SVG static VAR generator and Yide Yuntong platform, while also improving operation and maintenance efficiency and economic benefits. This successful case provides a useful reference for other companies' power quality transformation.
