Description
Technical Field
The invention relates to a control system of a natural gas long-distance pipeline compressor, in particular to a remote automatic control system of a natural gas long-distance pipeline compressor unit.
Background
Under normal conditions, the operation of the compressor unit is independently controlled by a unit control system/disc (UCP) provided by the compressor unit set, and each set of the compressor unit is provided with 1 set of the UCP. When the running unit has a fault, the UCP sends out a corresponding adjusting instruction or a stopping instruction, simultaneously transmits signals to the SCS and the dispatching control center, and starts the standby unit through central remote control or station control so as to meet the gas transmission requirement. A unit control system/panel (UCP) provided by a compressor unit set is installed in a station control room cabinet.
UCP is provided by compressor supplier, connected with SCS through standard data communication/network interface, to exchange data, according to the remote control requirement of dispatching control center and SCS.
The control system that current natural gas long distance pipeline mainstream compressor unit supplier provided has all possessed remote control function basically, and the main difference lies in the control function openness degree that provides, aspects such as ease of use degree and control effect. When different control systems of different manufacturers exist in the same gas station or a pipeline for parallel production, the remote dispatching center generally cannot control the control systems of the whole compressor unit in a unified and centralized manner. The common solution is to upload the control signals of each compressor set to a dispatching control center, and then the dispatching personnel manually or automatically control a single independent compressor set or a set of the same control system of the same manufacturer. And the control of the multi-brand machine combination station building can only depend on the control parameters of different machine groups manually coordinated by a dispatcher through experience.
Most of compressor units of the domestic natural gas long-distance pipeline gas station are provided with UCP control panels and have the functions of on-site and remote shutdown. However, in the same compressor station, if compressor units of different types of different manufacturers coexist, controllers of different manufacturers have compatibility problems and control difficulty. Therefore, various compressor units which can be controlled remotely and independently originally cannot be combined together for remote control, and functions such as remote combined startup, remote load distribution control, remote unit switching control and the like cannot be realized smoothly.
In the co-building station, compressor units of different manufacturers and different control systems can only be controlled by using respective operation stations in actual production. After the data is remotely transmitted to the dispatching control center, the data is also controlled on the basis of the compressor units of the same manufacturer, and different compressor units cannot be combined to be controlled.
In the current long-distance natural gas pipeline gas station, a plurality of compressor units of different control systems of different manufacturers exist. The whole compressor unit of the gas compression station cannot be subjected to process consideration and automatic load increasing and reducing control by an operation unit, and the load distribution control of the whole compressor unit of the gas compression station cannot be performed.
The existing compressor unit control system of the long-distance natural gas pipeline gas station generally has the problems of strong system specificity, unopened system, non-uniform data acquisition and the like. When a plurality of compressor unit control systems of different models of different manufacturers exist in one air compression station or one pipeline, how to integrate the control systems together for centralized and unified control becomes the most difficult problem for users.
The invention needs to consider the practical difficulty of the problems, and provides an effective solution by comprehensively considering the problems of cost, efficiency, construction period and the like on the premise of technically realizing automatic control of the natural gas long-distance pipeline compressor unit control system aiming at different brands of control systems of different manufacturers.
