Bộ điều khiển nhà máy điện thông minh SPPC2000

Product Description

The SPPC2000 is a dedicated plant-level controller solution for utility-scale renewable energy power plants. The device is responsible for collecting direct voltage and current samples from potential transformers (PT) and current transformers (CT) at the point of common coupling (PCC), calculating and executing real-time power regulation commands for hundreds of inverters or Power Conversion Systems (PCS) with ultra-low latency.

Key features

• Smart Power Control: Supports dynamic or fixed active power control based on setpoints, frequency control (P-F), reactive power control (Q or PF), and voltage control based on Q-U curves.

• Coordinated PV and ESS Control: Integrated coordinated control algorithm between the PV array and the energy storage system, minimizing Power Oscillation Damping (POD) within a frequency range of 0.1 Hz to 2.5 Hz.

• Ultra-Fast Dynamic Response: Plant-level dynamic reactive power response time within 30ms to 40ms, maintaining plant stability during sudden grid fluctuations.

• In-Depth Fault Recording: Supports instantaneous value recording (0.5ms cycle) and long-term Root Mean Square (RMS) voltage and current tracking for precise system fault analysis.

• High-Precision Time Synchronization: Supports IRIG-B high-precision time synchronization standard ($\le$ 1 ms) alongside conventional network time protocols including NTP.

Why Choose the SPPC2000?

• High-Precision Direct Sampling: Supports direct sampling of a 6U+6I circuit system, with current/voltage sampling accuracy reaching 0.2% and power accuracy reaching 0.5%.

• Comprehensive Simulation Model Support: Compatible with and provides comprehensive power system simulation models for reputable international software including PSS/E, DigSILENT, and PSCAD.

• Versatile Interface Interaction: Supports an intuitive embedded Web user interface and seamless integration with the Smart PVMS or SPMS2000 smart plant management system.

• Redundant Dual Power Supply Design: Supports flexible backup power inputs from both AC (90 V – 264 V) and DC (110 V / 220 V), preventing sudden device power loss.

• Hot Standby Operation Mode: Supports network configurations for Active/Standby or Master/Slave redundancy modes, maximizing operational reliability.

• Stringent Industrial-Grade Protection: Enclosure features an IP55 protection rating, C5-Medium anti-corrosion protection, and built-in Type II surge protection devices (SPDs) for both DC and AC sides.
