Title:
NEW TYPE OF POWER-GRID MEASUREMENT AND CONTROL SYSTEM USING POWER CARRIER TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2017/152312
Kind Code:
A1
Abstract:
Provided is a new type of power-grid measurement and control system using power carrier technology, comprising a central server (1), an electronic carrier generator (2), and several power-grid measurement and control gauges (5); said central server (1) and electronic carrier generator (2) are electrically connected to an optical fiber (3); said electronic carrier generator (2) and power-grid measurement and control gauges (5) are electrically connected to a connection cable (4); by means of the electronic carrier generator (2), the new type of power-grid measurement and control system using power carrier technology implements a system performing signal transmission by means of a power carrier, thus reducing wiring costs; at the same time, it is possible, by means of a transformer (T1), not only to couple a carrier signal, but also to isolate the communication circuit from the operating-frequency AC strong electricity, improving the reliability of the system; in addition, by means of a resonance network consisting of a third capacitor (C3) and an inductor (L1), an interfering signal is effectively filtered, improving the stability of signal transmission; a surge protection function is achieved by means of a bidirectional diode (TVS), effectively preventing high-voltage breakdown of a back circuit and improving the reliability of the circuit.
