Embodiment 1

[0057] Embodiment 1: For the start-stop control process of the compressor unit body, the present invention designs four control methods for the compressor unit to start up with one key, the unit to reduce and stop with one button, the unit to switch with one button, and the unit to automatically switch when the unit fails. The aforementioned control methods are used in the compressor unit. It is realized in the joint operation control system, which includes the operation terminal, the SCS station control system, the UCS unit control system, the UPS unit protection system, the MCP load distribution system and the compressor unit system. The one-key increase start of the compressor unit, the one-key decrease and stop of the unit, the one-key switch of the unit, and / or the control method for the automatic switchover of the unit as described in any one of the preceding.

[0058]Before the compressor unit is started, the relevant auxiliary systems should be started first, so that th...

Abstract

The invention provides a combined operation control method of compressor units, comprising: starting the hot standby control program of the external auxiliary system; when the hot standby control program of the external auxiliary system is in the hot standby state, starting the hot standby control program of the internal auxiliary system of the compressor unit; When the internal auxiliary system of the compressor unit is in the hot standby state and the compressor unit has no failure, the compressor unit starts up according to a predetermined sequence. Quickly start the compressor with one button at the center or station end, shorten the actual start-up process and time, and improve the timeliness of response to dynamic changes in pipe network pressure and flow. At the same time, the control methods of one-key increase start, one-key decrease stop, one-key switchover and automatic switchover of compressor unit failure are designed to meet the start-stop control requirements of station compressors under different process conditions.

Description

technical field [0001] The invention relates to the technical field of long-distance natural gas pipeline station compressors, in particular to a combined operation control method and system of a compressor unit. Background technique [0002] With the continuous development of my country's long-distance natural gas pipelines, the continuous advancement of the concept of smart pipeline network construction, the transformation of natural gas pipeline production management mode, and the continuous promotion of the regional management mode of compressor stations, the control level and control function of gas pipelines are put forward. higher requirement. As an important part of the long-distance natural gas pipeline, the compressor unit needs to realize the remote operation and automatic control of the compressor unit at the station and the control center under the premise of unmanned intervention. [0003] At present, on the one hand, the sequence of the process system involved...
