Code and Implication of the Auto-Compensation Capacitor Controller

Introduction to the Auto-Compensation Capacitor Controller
ZHIMING brand of Reactive Power Auto-Compensation Controller. This series of controllers employs a high-performance single-chip microcomputer as its hardware foundation. It fully utilizes the computer’s high-speed operational capabilities and logical judgment to achieve true digital intelligence. With advanced technology, comprehensive functionality, robust EMC performance, reliable operation, precise branch compensation, and a streamlined design, these controllers are the preferred solution for capacitive screen manufacturing.
Structure Features of the Auto-Compensation Capacitor Controller
● Employs True RMS AC Sampling Technology
● Features Digital Integration and Filtering
●Utilizes Single-Chip Microcomputer Control Technology to Achieve Intelligent, Automated Power Grid Reactive Power Compensation
●Robust EMC Performance: Withstands 2000V surge pulses (per IEC 61000-4-5) directly from the power supply. Ensures crash-free operation, data retention, and stable performance. Digitally displays grid parameters: power factor, over-voltage conditions, current, and control settings.
●Automatic Self-Calibration: Eliminates the need for manual CT ratio configuration. Automatically adapts to varying capacitor bank sizes and grid parameters.
●Automatic Phase Sequence Detection and Correction
●Dual Operating Modes (Manual/Automatic): Simplifies installation, commissioning, and testing. Integrated overvoltage protection rapidly disconnects capacitor banks.
●Intuitive HMI: Streamlined operation, commissioning, and real-time monitoring via direct-view digital interface.
●Low-Burden Current Sampling: Input resistance < 0.05Ω, enabling direct connection to CT secondary circuits without external shunts.Employs True RMS AC Sampling Technology.
