Centralized Cooling & Heating + Energy Storage New Energy Load

Located in the Nanjing Jiangbei ,Energy Station #3 serves as a pivotal municipal comprehensive energy project. It integrates centralized cooling, centralized heating, and energy storage peak-shaving systems. The station operates under a complex mixed load of traditional thermal equipment and new energy storage devices. This creates significant challenges, including large peak-valley differences, frequent load switching, and unstable impact currents. Consequently, the power distribution system is held to exceptionally high standards regarding intelligence, stability, and anti-fluctuation capabilities.

To address the specific pain points of fluctuating hybrid loads in new energy scenarios, Changyun Electric has customized a professional 10kV intelligent power distribution solution. The core technical highlights are as follows:

• Gas Insulated RMU (SF6 Fully Sealed)
  • Zero Exposure & High Protection: Adopts a fully sealed gas-insulated structure with zero external exposed live parts. It offers superior dust-proof, moisture-proof, and anti-condensation performance, perfectly adapting to the all-weather continuous operation required by energy stations.
  • Compact & Grid-Friendly: Its compact size eliminates the need for extensive civil construction, fitting the intensive layout of urban energy stations. Technically, it effectively resists voltage fluctuations caused by energy storage charge-discharge impacts and suppresses grid harmonic interference.
• Medium Voltage Switchgear Centralized Control
  • Intelligent Load Management: Realizes unified incoming line metering, load shunting, and fault protection for cooling, heating, and energy storage hybrid loads.
  • Rapid Isolation: Equipped with advanced intelligent protection modules, the system can quickly isolate abnormal loads. This prevents mutual interference between traditional thermal loads and new energy storage loads, ensuring the independent and safe operation of each functional module.
• Customized Box Transformer for Fluctuating Loads
  • Optimized for Stability: Features a transformation and voltage regulation design specifically optimized for new energy fluctuating loads, boasting strong overload resistance.
  • Adaptive Thermal Management: The built-in temperature control and heat dissipation system adapts to seasonal peak load changes. This stabilizes output voltage and effectively solves power quality instability caused by frequent load switching.
• Remote Intelligent Measurement & Control System
  • DTU Automation: Matched with DTU distribution automation terminals to support remote data monitoring, real-time fault alarms, remote switching operations, and intelligent load regulation.
  • Unattended Operation: Fully realizes the unattended intelligent operation of the energy station's power distribution system, significantly reducing manual O&M costs.

Changyun Electric provides a robust, long-term service guarantee system to ensure the stable and efficient operation of urban comprehensive energy projects:

• Extended Warranty: We offer a multi-year full equipment warranty to ensure complete peace of mind for our clients.
