Hongshanzui Integrated Automation System II Power Design

Set a separate set of LCU, all participants before the pool of integrated automation monitoring and control equipment by the ICU to achieve. The LCU through optical Ethernet and integrated control system connected to the host computer. In the control room can be completed before the pool of all equipment monitoring and control functions. 1.6 Set the video system design hydropower enterprises to set up a more modern scientific and perfect video surveillance systems have become a trend and trends. By day and night surveillance cameras set up key parts can effectively reduce and prevent fires, floods and other accidents, but also enables staff to monitor realized access, illegal access, management of such cases in the post. Through the establishment of the relevant parts of the camera to read the data and the observation of real images to realize that in the control room operators to understand the relevant circumstances, to reduce operator work intensity, while achieving greater efficiency. 10 second camera station location and monitoring role in the arrangements shown in Table 1. Table 1, set the serial number of video surveillance installation location point of the main objectives of Type 2 integrated surveillance system outlined in the secondary station from the station if the use of integrated automation system that can effectively reduce the cost of renovation. Compared with the traditional design of each subsystem independently,[link widoczny dla zalogowanych], through an integrated design automation and extensive use of field bus to achieve information exchange between the various subsystems, can significantly reduce investment in the cable to reduce the hard-wired interconnection between systems, thus certain extent, reduce the on-site installation, maintenance staff workload. Advanced Automation System station has the following characteristics: (1) system-wide open network system in line with international standards. Network uses a two-story structure, the first layer is the site (plant) level network, providing 1OM/100M Ethernet interface, supports standard TCP / IP network communication protocol; the second layer is present to control the level network, providing CAN field bus network, communication rates up to 1Mbps; (2) functional, set of monitoring and control, automatic synchronization, exchange volume collection, excitation system, speed control system, protection and other functions into one, and offers a variety of communications and external systems interface; (3) provide a flexible programming language Ladder Ladder richer and more functional modules, intuitive visual flow chart programming language. Modular program structure,[link widoczny dla zalogowanych], ladder and call flow between themselves; (4) support remote programming and debugging, and support for remote diagnosis and Web browsing; (5) of each module,[link widoczny dla zalogowanych], the module asks a standard bus interface and common software Statute,[link widoczny dla zalogowanych], it Zuwang Fang, flexible configuration. Station integrated automation system shown in Figure 2. (Continued on page 13) * Power monitoring Panmiao Miao, et al ABBProcessProtal technology in the Three Gorges power station computer monitoring system of comprehensive long-term data server for data records. Record template defines the data storage, such as time interval, storage time, dead areas. Access to data may take the form of trends and logs. Figure 4 shows trends in data access flow diagram is an important tool for industrial control. ProcessPortal for the operator to provide a powerful trend display. Trends show the real-time data and historical data seamlessly, you can move without having to consider the time range of data from where you can real-time tracking using the time shift function, and current data to compare with previous data. Trend indicates that contain multiple curves,[link widoczny dla zalogowanych], and can handle the associated attributes. Typically, the trend shows the relationship between the value at any time to ask, but in some cases need to show the relation curve between two values, ProcessPortal have this feature. 3 Conclusion ProcessPortal a standardized technology, range of information for the whole plant monitoring, control and management provides a single window interface. Systems provide intuitive pop-up text menu, the user can very easy to operate and manage, and access control system from the production process, steps, until the whole plant within the scope of information flow. Computer monitoring system in the power station man-machine interface based on ProcessPortal, intuitive, easy to operate, fully functional, the Three Gorges power station is a reliable guarantee for the safe operation of generating units. (Continued from page 1O) Figure 2 hydropower integrated automation system integrated automation system in Figure 3 the conclusion as the core of the safe operation of power plants, and plant safety and economic operation are closely related. If the station through the use of integrated automation system, can greatly improve the automation level of the secondary station to improve the safety and reliability, so as to create a better benefit the secondary station. Two power plants in Xinjiang, as one of the earliest construction of the station, such as the successful transformation and safe operation, will create a good demonstration effect, and thus the production of construction of the border to play a more active role. 13
