Shanghai Xinmin Light Rail Control Center Power Monitoring System

Abstract: Shanghai Xinmin Light Rail Control Center power monitoring system information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. Preface With the rapid development of my country's national economy, the development of urban transportation has become the top priority of my country's urban construction. Nearly 15 cities in my country will vigorously develop and build rail transit in the Tenth Five-Year Plan, and are currently under construction. The main ones are Shanghai. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article on the power monitoring system of the Shanghai Xinmin Light Rail Control Center. 1. Preface With the rapid development of my country's national economy, the development of urban transportation has become the top priority of my country's urban construction. Nearly 15 cities in my country will vigorously develop and build rail transit in the Tenth Five-Year Plan, and are currently under construction. The main ones are Shanghai, Beijing, Tianjin, Guangzhou, Shenzhen, Nanjing and other cities. Taking Shanghai as an example, there are nine rail transit lines that will be put into operation by 2005, and a total of 17 lines are included in the Shanghai rail transit construction plan, with a total length of 780 kilometers. After technical and market research and demonstration, Xinhua Company has taken automation in the field of rail transit (including large railways) as a new development direction for the company since 2000. In 2001, Xinhua Company participated in the bidding of the power monitoring system (including the automation in the substation) of Shanghai Rail Transit Line 5 (Xinmin Light Rail Line), and won the bid for both technology and business. The bid for the northern extension of Line 1 was awarded. In 2001, Xinhua Company won two consecutive bids among the three localized rail transit lines in Shanghai. At present, the power monitoring system SCADA system of Shanghai Rail Transit Line 5 (Xinmin Light Rail Line) undertaken by Xinhua Company has been put into operation. 2. Implementation plan of power monitoring system for Xinmin light rail line 2.1 Overview of Shanghai Xinmin light rail transit project power monitoring system engineering , except for the Xinzhuang Station line (about 0.41 kilometers), which is a ground line, all of which are elevated lines. There are 11 stations and 1 parking lot. There are 18 substations along the power supply part of the project: Xinzhuang Station traction substation, Xinzhuang Station step-down substation, Xincheng Station step-down substation, Yindu Road Station traction and step-down hybrid substation, Zhuanqiao Station Station traction, step-down hybrid substation, Beiqiao station step-down substation, Jianchuan Road depot traction, hybrid step-down substation, Jianchuan Road depot step-down substation, Jianchuan Road station step-down substation, Dongchuan Road Station traction and step-down hybrid substation, Jinping Road Station step-down substation, Huaning Road Station traction box-type substation, Huaning Road Station step-down substation, Wenjing Road Station step-down substation, The step-down substation of Tianxing Road Station, a step-down substation is set up in the control center, a 110/35/10KV main substation is set up in the Jianchuan Road depot, and a 35/35KV main substation is set up at Yindu Road Station. Shanghai Xinmin Light Rail Transit Power Monitoring System SCADA system is composed of the central power monitoring system located in the control center and the substation integrated automation system and its communication channel located in each substation. The central power monitoring system is responsible for the above 18 Real-time monitoring of substations and catenary electric isolation switches to realize automatic control and management of substations. 2.2 Control Center Power Monitoring System Architecture The configuration of Shanghai Xinmin Light Rail Transit Engineering Power Monitoring System Center monitoring system is shown in the figure below: Its main features include: A) The system network adopts CISCO's 10/100M dual-speed adaptive switch. This scheme configures dual redundant main network, each network adopts a CISCO3548 switch, and supports access to 48 computers. CISCO3500 series switches have a switching capacity of up to 10.8G, which provides a reliable guarantee for non-blocking data flow. In addition, this series of switches also have the expansion capability of Gigabit fiber uplink, leaving room for future high-level network interconnection. B) Compaq products are selected for the server and disk array of the control center system, and the Unix support platform with high performance, safety and reliability, and no downtime is adopted. The database server is composed of two Unix servers and a disk array, and the shared access arbitration and switching of the two servers to the disk array are realized through the CompaqTruCluster dual-machine sharing software. The disk configuration scheme in the configured disk array adopts RAID5, which provides a cost-effective solution for data security. COMPAQ's Alpha server, COMPAQ's RA series disk array, and TruCluster dual-machine sharing software form a complete set of COMPAQ database servers in this system. All hardware and software, constitute a complete solution for dual-machine sharing. C) Data collection adopts industrial computer and the latest dual-machine switching terminal server, keeping up with the latest technological development. The TCPServer in the dual-machine switching terminal server uses an IP port to provide a link for the main and standby machines to avoid the time interval for establishing a link in the dual-machine switching. And make the two machines share a set of terminal servers,It provides unified data for the hot standby of the primary and secondary hosts. D) The human-machine workstation of the master station system uses CompaqAlphaUnix workstation, which is high-performance, safe and reliable, and does not stop, ensuring the continuity of operation; E) The communication machine of the system is also the WEB server of the system, using a PC server.
