Simulation operation safety early warning method and system of long-distance pipeline substation

Abstract

The invention relates to simulation operation safety early warning system of a long-distance pipeline substation, comprising a control system and a power supply circuit. The control system comprises a PLC (Programmable Logic Controller) control system, a rating result singlechip system and an operation and indication system, wherein various switches of the systems are all connected with the input end of the PLC, and the output end of the PLC is connected with four output control ports and three operation outputs; the four output control ports are respectively connected with various state indications and display controls; and the output end of the PLC is also connected with the rating result singlechip system. The power supply circuit is characterized in that the high-voltage side of a main transformer inlet wire adopts an inner bridging line, and two main transformers and two power supply inlet wires are adopted to respectively simulate two voltage classes; a high-voltage connection is divided into two sections, wherein the 1# inlet wire of the 1# main transformer is connected with an I-section PT (Potential Transformer) and a plurality of pump motors; the 2# inlet wire of the 2# main transformer is connected with an II-section PT, a standby, a station transformer and a plurality of pump motors, and the two inlet wires are contacted and connected by a bus; and single busbars are adopted for subsection connection of low-voltage power supply.

Description

technical field [0001] The invention relates to a long-distance pipeline substation operation safety early warning method and simulation training system and a long-distance pipeline substation simulation operation safety early warning method and system, and relates to the technical field of circuit emergency protection devices, power supply and distribution circuit devices, and pipeline systems . Background technique [0002] At present, in addition to learning professional knowledge at school, the current training method for operating personnel in substations of long-distance pipelines is to practice in substations. Although this training method is effective, it is not ideal; due to the characteristics of power production and operation It is the continuity of its production, so this feature determines that the operators can only "see, listen, and think" in their daily work, but not practice. Once there is an abnormality or an accident that requires hands-on operation, it i...
