Construction significance
Oil and gas pipeline transportation can not only avoid the unbalanced impact of climate and other reasons on transportation, but also can be operated flexibly and stably according to the market demand, which is conducive to the integration of production and sales. It also has the province of investment, transportation safety, low operating costs, and low loss. Its advantages can reduce the pressure on railway transportation, accelerate the development and management of China's oil and gas pipeline network transportation system, improve the structure of China's oil and gas transportation, and help China's energy security, supply of demand protection and economic development. It is the related companies that further enhance the competitiveness of the market. The important way.
Through the construction of an advanced monitoring and data acquisition system, referred to as the SCADA system, through the host and the microprocessor-based remote terminal device RTU, PLC and other data acquisition, to achieve the entire industrial network monitoring, in order to ensure the safe operation of oil and gas pipeline transportation And optimal control
Oil pipeline system structure
ACC has a wealth of experience in the oil, gas and pipeline industries and advanced system design methods. It provides a set of proven, safe, and complete solutions for the characteristics of oil and gas pipelines.
SCS Station Control System and SIS-Safety Instrumented System are installed on the manned process station along the pipeline, and remote control terminal equipment (RTU- Remote Terminal Unit. SCS, SIS, and RTU are the basis for ensuring the normal operation of the SCADA system and are the remote execution unit for controlling the dispatch, management, and control commands of the center. SCS, SIS and RTU not only can independently complete the data collection and control of the process field, but also transmit relevant information to the dispatching control center and accept the commands issued by it.
Oil and gas pipeline control system can be divided into three layers:
Data acquisition layer: mainly refers to the collection and control of field data through PLC and RTU. The station, valve room, etc. are transmitted to the station control room and dispatch center through the optical fiber, and the data is achieved through the SCADA system of level 2. Acquisition and control.
Station level control: Mainly complete the data collection and data processing of the process, monitor production operation parameters, main equipment status and protection, control valve opening and closing, main parameter adjustment and safety interlock protection, ESD protection and water hammer protection, etc. Features.
Dispatch center: adopts the master-slave dispatch center method to remotely monitor and schedule all station and valve rooms through communication.
System functions
Process flow mainly includes: dispatch center, station, valve room
Dispatch Center System
â– Basic design of main control center
â– The dispatch center establishes the center SCADA, batch transmission, simulation and WEB functions
â– Basic design of backup control center
â– The standby center plays the role of monitoring and scheduling across the entire network when there is a problem with the link to the main control center.
Station control system
The station control system mainly completes the data collection and data processing of the process, monitors the production operation parameters, the main equipment status and protection, controls the opening and closing of the valves, the adjustment of the main parameters and the safety interlock protection, ESD protection, water hammer protection, etc. Features. As the remote control unit of the SCADA system, the station control system is the basis for ensuring the normal operation of the SCADA system. It is the remote execution unit for dispatching, controlling, and controlling commands of the control center, and is the most important monitoring level in the SCADA system.
Valve Room RTU System
The valve room RTU system monitors the production parameters of the valve chamber, controls the opening and closing of the valve, the adjustment of the main parameters, and the safety interlock protection, ESD protection, water hammer protection and other functions. It is the dispatching and management of the station scada system and dispatching control center. The remote execution unit controlling the command.

System Features
Advancement
Adopt configuration software with standard functions and SCADA system with advanced industrial technology. Make full use of the existing high technology to ensure that the system investment achieves the best benefits and reaches the leading domestic level.
reliability
The use of high-quality equipment to complete the system architecture not only guarantees stable and reliable operation of the system, but also greatly reduces the maintenance workload after commissioning and saves on secondary investment, while avoiding losses caused by system failures.
Openness
The system must have a flexible structure and good openness, and provide good communication compatibility between information management software and on-site smart devices.
safety
The system has powerful maintenance and diagnostic functions to ensure the safe and reliable operation of the system. The system has the functions of monitoring and controlling the main links and can prevent illegal users from exceeding their rights.
Economical
The high-quality, high-standard equipment constitutes the system, which greatly reduces the maintenance and maintenance costs of the system during operation; it can provide a good interface for future system scale expansion and function expansion, and protect the user's investment.
