Abstract

The invention discloses a distributed control system SOE testing device, which comprises a control unit, a human machine interface, an output unit and a charge and power supply unit, wherein the humanmachine interface and the control unit perform two-way communication; the output unit is connected to the control unit; and the charge and power supply unit is connected with the human machine interface, the control unit and the output unit respectively. The invention also discloses a distributed control system SOE testing method. The method can conveniently test the SOE resolution of the distributed control system and timely discover the problems of the SOE system.

Description

technical field [0001] The invention relates to a distributed control system SOE test device and a test method, belonging to the field of thermal automatic control. Background technique [0002] With the increasing scale and complexity of thermal power units, the power plant has higher and higher requirements for safe operation. When a unit fails, maintenance personnel need to quickly find out the cause of the accident and take corresponding measures. This requires Recall events and print them. SOE (Sequence Of Event) is a subsystem of the distributed control system. It records relevant information when an accident occurs with millisecond-level resolution, and can help maintenance personnel quickly analyze faults and find out the cause of the fault. For example, the Chinese patent application number 201120355878.9 . [0003] According to the requirements of DL / T659-2016 "Acceptance Test Procedures for Distributed Control System of Thermal Power Plants", the resolution of S...
