Intelligent control system for distribution roomThe development of modern industrial technology has put forward higher requirements for the reliability and intelligent governance of power distribution systems. The widespread application of microprocessor technology and the significant improvement in the reliability of computer systems have led to the rapid development of intelligent electrical components and the emergence of intelligent electrical governance systems. The development of comprehensive protection and system monitoring (SCADA system) for medium and high voltage systems of 6kV and above, and its application in power systems.
Intelligent control system for distribution roomTheir applications have their own characteristics:
The same standard has been established and has demonstrated its advantages in specific application areas. The advantages of fieldbus technology mainly include:
(1) Save hardware investment. The intelligent devices of the fieldbus system are dispersed on site and can directly perform control and calculation functions, reducing the need for a large number of transmitters, regulators, computing units, etc. It also eliminates the need for signal transmission processing units and their complex hard wired connections in DCS systems, saving considerable hardware investment and reducing the footprint of control rooms.
(2) Save installation costs. The wiring of fieldbus systems is very simple. Several or even hundreds of devices can be connected to a communication bus, saving installation accessories and greatly reducing installation workload. The workload of design and wiring verification is also greatly reduced. According to the data, compared with DCS, the installation cost of fieldbus system can save more than 60%.
(3) Reduce maintenance costs. Due to the self diagnosis and certain fault handling capabilities of on-site control equipment, and the transmission of relevant information to the control room through digital communication, users can monitor and query the operation of all equipment in real time, timely understand maintenance information, so as to analyze and eliminate faults early and shorten maintenance downtime. Meanwhile, due to the simplified system structure and simple wiring, the maintenance workload has been reduced.
(4) System integration is simpler and more flexible. Users can choose products from different manufacturers to integrate the system, avoiding or reducing the trouble caused by incompatible protocols and interfaces in system integration.
(5)Intelligent control system for distribution roomImproved the correctness and reliability of the system. Due to the intelligence and digitization of fieldbus devices, compared to analog signals, it fundamentally improves the accuracy of measurement and control, reducing transmission errors. At the same time, due to the simplification of the system structure and the strengthening of internal functions of on-site intelligent devices, the round-trip transmission of signals has been reduced, and the devices can work without relying on the network, improving the reliability of the entire system operation.
