Abstract

The invention relates to an intelligent high-order scheduling and operation and maintenance system and method for a gas transmission pipe network. The system is characterized in that the system comprises: an SCADA systemused for collecting the operation parameter data of the gas transmission pipe network in real time; an intermediate database used for storing the operation parameter data of the gas transmission pipe network and the historical gas consumption data of the user in real time; a pipe network integrity management system used for determining limited pressure and limited flow of field station equipment and gas pipelines in the gas transmission pipe network in real time and performing online early warning on abnormal data; a scheduling analysis system for obtaining a scheduling auxiliary analysis result of the gas transmission pipe network; a dispatching command system used for determining a decision result; and a control system used for generating an instruction according to the determined decision result so as to control each station device of the gas transmission pipe network to work. The system and the method can be widely applied to the technical field of operation scheduling of natural gas long-distance pipelines and gas transmission pipe networks.

Description

technical field [0001] The invention relates to an intelligent high-level scheduling and operation and maintenance system and method of a gas transmission pipeline network, and belongs to the technical field of long-distance natural gas transmission pipelines and gas transmission network operation scheduling. Background technique [0002] At present, with the gradual expansion of the scale of the gas transmission pipeline network system, the structure and facilities of the pipeline network tend to be more complex, and the scheduling and management of optimizing natural gas pipeline transmission is also more complicated. Universal networking, large-area dispatching, and intelligent operation of the gas pipeline network have become new development trends. Unlike many pipeline companies in Europe and the United States, which are responsible for independent transportation and dispatching, China is characterized by centralized dispatching of large-area networked pipelines However...

Problems solved by technology

[0004] However, there are obvious problems in the existing methods, including the relatively simple content of the centralized control system, relatively elementary technical means, multi-program hydraulic optimization offline in the centralized control system, integrity evaluation independent of the control system, intelligent pressure regulation measurement methods and remote control systems. The degree of intelligence of the metering handover is low and it is difficult to effectively integrate with the current centralized control system, resulting in a single function of the current dispatching and operation and maintenance system, which cannot integrate pipe network balance, energy measurement, local calorific value adjustment, risk assessment and production operation and maintenance And other functional requirements such as multi-user capacity allocation, component tracking of multiple gas sources, calorific value adjustment, and multi-user capacity allocation under the open conditions of third parties are still in the blank stage from the perspective of production scheduling, and are not suitable for intelligent management. web development needs
