Device Introduction
B Intelligent reactive power compensation device is carefully developed and designed to meet the needs of reactive power compensation for high-voltage lines. It is an automatic control device realized by microcomputer technology. The control device effectively and reasonably controls the switching of the parallel capacitor bank to improve power factor, reduce line loss, and improve voltage quality.
B The intelligent reactive power compensation device can control the switching of one or two parallel capacitor compensation devices according to the line voltage and line current, and at the same time, it can protect the capacitors according to the capacitor current and line voltage. This device has multiple sets of built-in control strategies, and the control strategy can be selected remotely and the control settings modified. It has R, radio frequency and other communication methods to choose from.
The wireless data communication of B intelligent reactive power compensation device uses the latest R mobile communication technology and mobile communication network as the transmission medium, taking advantage of R's high resource utilization, high transmission rate, short access time and other characteristics as the device. Data transmission channel with the dispatching master station.
Features of the system:
★ Advanced technology: The communication adopts R wireless communication technology, with no distance limit. The system is convenient for networking and is domestically advanced.
★ High reliability: Using a (system-on-chip) processor, the bus does not leave the chip, and the unique software watchdog and hardware watchdog monitoring technology ensures the safety and reliability of the system to the greatest extent.
★ Stable performance: The secondary voltage and current sampling loop is input through a transformer isolation, and has no electrical contact with the primary loop. The remote signaling input loop adopts photoelectric isolation technology, and the input loop has an anti-surge high-voltage circuit. The remote control output loop adopts photoelectric isolation and The two-level isolation communication interface of the relay is equipped with photoelectric isolation.
★ High cost performance: The system integrates measurement, control, protection, communication and other functions. The device can be operated and maintained remotely through the Internet. R wireless communication costs are low, and the channel is maintenance-free. It can be operated and maintained nearby through R radio frequency communication.
★ Novel human-machine interface: using Chinese character LCD display and keyboard, using multi-level password protection, simple operation and convenient maintenance.
★ Excellent reactive power compensation algorithm: The extended nine-area diagram algorithm with pre-judgment function is used to avoid repeated switching of parallel capacitors during the compensation process.
