LONGi New Energy Technology Industrial Park is a comprehensive industrial park integrating R&D, manufacturing, sales and service of new energy technology in Mengsu Economic Development Zone, Ordos, Inner Mongolia, with its main business covering photovoltaic modules, cells, power station construction and other fields.
In order to meet the safe and reliable operation of the project, CET provided power monitoring system solutions and corresponding power monitoring and other secondary intelligent terminal products for the monocrystalline plant of LONGi New Energy Technology Industrial Park.
The CET power monitoring system solution adopts a hierarchical distribution and open structure design, and configures power meters distributed in several distribution rooms, which improves the safety and economic operation level of the high and low voltage distribution rooms of the monocrystalline plant in LONGi New Energy Technology Industrial ParkAt the same time, the whole plant is controlled, coordinated and managed, fault analysis and complex data processing are carried out to provide highly reliable and high-quality operation and management means for enterprise managers.
In the monocrystalline project of LONGi New Energy Science and Technology Park, CET has a deep understanding of customer needs to escort the project. The power monitoring system server collects the data of the microcomputer comprehensive protection, instrument, DC power supply, diesel generator, transformer thermostat in the distribution room through the industrial Ethernet interface optical fiber, and can issue control instructions, and a monitoring system can be used to distribute and manage the monitoring data in the independent area.
In the power control room of the B101 workshop, a power monitoring station is set up, which can display, operate, and query information data, and set up a historical database, open the communication structure to the energy management system, and transmit data according to its requirements.
In the B101 and B102 workshop high-voltage distribution room is equipped with power monitoring communication cabinet, the cabinet includes an independent integrated background system host, display screen, intelligent communication management machine, network switch and other communication accessories, used to monitor 10kV equipment and transformers, low-voltage incoming lines, bus connection, compensation devices, DC screens and diesel generators.
In the B101 and B102 workshops of the low-voltage power distribution room, waste water station, argon station and other monomer configuration of power monitoring communication cabinet, the cabinet includes intelligent communication management machine, network switch and other communication accessories for monitoring low-voltage electrical equipment low-voltage incoming line, bus connection, compensation device, DC screen and diesel generator and on-site distribution cabinet.
In the waste water station, argon station and other monomer configuration of power monitoring communication cabinet, the cabinet includes intelligent communication management machine, network switch and other communication accessories for monitoring the electrical equipment in the area.
The power monitoring communication cabinet transmits the signal to the power monitoring system background of the power control room. The power supply of the power monitoring terminal is taken from the general control UPS of the automatic force central control room, and the UPS is no longer configured separately, and the power supply of other communication cabinets is taken from the DC screen inverter or UPS nearby.
(2) Real-time monitoring data of tray-mounted multi-functional measurement and control meters
In addition to the highly reliable power monitoring system, the deployment of on-site intelligent terminal equipment is also crucial to the safe and stable operation of the project.
CET has also deployed nearly 10,000 96-type disk-mounted multi-functional measurement and control meters in the high and low voltage cabinets and distribution boxes in the factory workshop, including CET CMC-S963 and PMC-33M-A three-phase digital multi-functional measurement and control meters, etc., which are connected to the power monitoring system to ensure real-time monitoring of factory electricity consumption, customized peak and valley report analysis, and demand.
It can not only calculate the full-day, full-month peak-to-valley level electricity of the 10kV circuit at regular timing, day and month, but also form statistical reports that can be analyzed. It can also calculate the current effective value, active and reactive power, the effective voltage value of each level of bus, and the power factor value (including the maximum, minimum and average value in a fixed period of time).Cumulative value of active and reactive power;harmonic data analysis, etc. Generate clear, easy-to-read daily load curves and bar charts.
PMC-33M-A takes industrial-grade microprocessor as the core, has fast processing speed, can provide accurate three-phase voltage, current and power and other basic measurement data, and has the functions of time-of-use billing, demand calculation, harmonic calculation, historical power recording, maximum value recording, and fixed value over-limitThrough RS-485 communication mode and host computer to achieve data exchange, intelligent power management can be realized.
PMC-S963 series three-phase digital multi-function measurement and control meter, with industry-grade microprocessor as the core, fast processing speed, has a very cost-effective, can provide accurate three-phase voltage, current and power and other basic measurement data, and has the functions of time-sharing billing, demand calculation, harmonic calculation, historical electric energy recording, maximum value recording, fixed value exceeding the limit, etc.
The multi-functional measurement and control meter used in CET Power Technology Industrial Park is a mid-to-high-end multi-function meter product independently developed by CET Power Technology, which has rich functions such as measurement and metering, time-of-use billing, power quality monitoring, data monitoring, etc., with accurate data and easy to use. Alarm in advance to effectively avoid accidents and reduce losses caused by accidents.
