Abstract

The invention provides a relay protection wiring comprehensive operation training system against the demands on daily maintenance and staff training work of relay protection of a power transmission and transformation system; and the system adopts real protection elements for providing a platform for leaning the principles of relay protection, feeling the real protection acting process, grasping intelligent training of the relay protection wiring method and checking for staff. The relay protection wiring comprehensive operation training system comprises a high simulation analog screen, a signal collection module and a background PC machine and software system which are sequentially connected, wherein the high simulation analog screen adopts real relays used on a secondary loop, and the wiring of sockets is arranged according to the features of the secondary loop; the high simulation analog screen mirror expands the front surfaces and the back surfaces of a variety of relays to the same plane; and the PC machine and software system comprises a main menu, a communication control module, a learning module, a process demonstration module and an examination module.

Description

technical field [0001] The invention relates to a comprehensive operation training system for relay protection wiring, which belongs to the field of electric power systems. Background technique [0002] When the power system operates from normal conditions to faults or abnormal operations, its electrical quantities (current, voltage, and phase angle between them, etc.) will change significantly. Relay protection uses electrical mutations to identify Whether the system has a fault or an abnormal operating state, the type and scope of the fault are detected according to the comparison of the measured value of the change of the electrical quantity with the electrical parameters of the system when the system is normal, so as to selectively remove the fault. A general relay protection device is composed of measuring elements, logic elements and executive elements. Since the reform and opening up, the rapid development of my country's economy has stimulated the rapid development ...
