With the continuous improvement of the modernization level of urban construction in our country, high-speed rail has become an important part of urban transportation. The medium and low voltage power distribution system of the station not only ensures the normal and safe operation of the high-speed railway, but also takes on important tasks such as emergency rescue, evacuation, and firefighting in case of failure and fire. The medium and low voltage power distribution system of the station directly affects the safety of people's lives and property.
There is a problem:
1. The popularization of intelligent power distribution is not in place.
2. The degree of "three remotes" of telemetry, remote signaling and remote control is low.
3. Various faults and alarm events such as parameter overruns in the power supply and distribution system cannot be discovered in time.
Our values:
Chuanglian Huitong Electric Box Substation actively participates in public building power distribution automation construction projects, continuously expands the field of intelligent power distribution, and provides key products and solutions such as intelligent primary power distribution equipment and power distribution automation, covering R&D, design, production, sales and services. The entire value chain integrates high-quality products and solutions under a unified architecture to improve the real-time monitoring, analysis, optimization capabilities and management level of the distribution network, save investment and operating costs for power grid customers, and boost the development of the power grid. Shift towards intelligence.
High-speed rail intelligent power distribution solution:
1. The high-speed railway power distribution system basically consists of power distribution at the station hall or platform level and general monitoring power distribution. That is, each rail line is equipped with a power distribution system at each station, and finally all sub-stations are centralized at the main station for centralized monitoring.
2. The main station can adopt the extension management mode, collect the power distribution parameters of each channel and upload them to the extensions, and then connect the extensions of each branch station to the main monitoring center through optical fiber connection, and be managed by the main monitoring host.
3. Depending on the scale and requirements of the high-speed railway, the requirements for the intelligent power distribution system will be different, but in essence, all terminal data are collected through multi-functional power meters and uploaded to the host computer system through the communication bus. After professional System software is used to monitor and control smart buildings.
4. The intelligent power supply and distribution system can be divided into three layers from a structural point of view: on-site I/O, communication management layer and central control layer. Among them, the control layer is the control core of the entire system, monitoring and controlling the operation of the power supply system, and can also be used for the interface of human-machine dialogue, data processing and storage management; the field I/O is used for field equipment status signals and operating parameters. collection, and control operations on field equipment.
The power distribution room is usually equipped with several sides of transformers, uninterruptible power supplies (EPS), DC panels, diesel generator sets, and high/low voltage distribution cabinets. Usually, power meters are configured on the power distribution cabinet for terminal data collection.
High-speed rail passenger dedicated line power solution:
The design of the remote box transformer for the passenger dedicated line fully takes into account the high reliability and maintenance-free needs of the high-speed rail power system. The high-voltage ring network switch uses an SF6 fully insulated and fully sealed inflatable GLS switch cabinet, a dry-type transformer, and an IBM network cabinet. , using joint venture brand circuit breakers, the switches are all electrically operated, and the signals are uploaded to the remote control system to achieve three remotes. Its configuration is more high-end and its design is more user-friendly. Ensure the safety and punctuality of high-speed trains and meet passengers’ needs for fast, comfortable, safe and punctual travel.
