Abstract

The invention relates to a double-redundancy industrial Ethernet data exchange unit, which comprises an excitation regulation cabinet, an excitation rectifier cabinet and a deexcitation protection cabinet. The device is characterized in that: a double industrial Ethernet exchanger is in series connection with the excitation regulation cabinet, the excitation rectifier cabinet and the deexcitation protection cabinet; and the excitation regulation cabinet, the excitation rectifier cabinet and the deexcitation protection cabinet are connected with the double industrial Ethernet exchanger by network transmission lines respectively. Due to adoption of a double Ethernet interface, a double Ethernet exchanger and a double network transmission line, the reliability of data communication in an excitation device is greatly improved and the communication transmission speed is fast.

Description

technical field [0001] The invention relates to the field of motor excitation control, and mainly relates to a dual-redundant industrial Ethernet data exchange device used for data exchange between a regulator in an excitation device, a rectifier cabinet, and a de-excitation protection cabinet. Background technique [0002] The excitation device provides adjustable excitation current for the operation of synchronous generators or motors. The device generally consists of an excitation regulation cabinet, one or more excitation rectifier cabinets, and one or more de-excitation protection cabinets. The excitation adjustment cabinet is the control center of the whole device, and the excitation adjustment cabinet contains two sets of regulators with the same structure and function. The excitation control cabinet must complete the collection and preprocessing of control signals, accept external control instructions, perform PID calculations, complete logic judgments, send control ...
