Factory Online Energy Monitoring Solution deployed in a certain factory in Saudi Arabia

0.Project Background: One of our party A customers in KSA want a entire Online Energy Monitoring Solution (mainly of electricity) for their factory machines. Their basic requests are "remote meter reading", "auto-generated daily&monthly&yearly energy consumption report for every machines and factory's overall power consumption". In other words, they want to realize a digitalization of energy monitoring for their all factory machines so that they could set up energy saving plan accordingly.   1.Factory Overview: (1) The factory could be devided into 3 Areas for power consumption monitoring.(2) Area 1 was Main Power Distribution Room. Only 1 main incoming circuit 3-phase here need to be monitored. Circuit's rated current is 2500A AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by busbar with the size of 110mm*50mm (Cross Section). (3) Area 2 was 1st workshop with 12 machines 3-phase needed to be monitored. Each machine was powered by 1 circuit 3-phase. Circuit's rated current is 400A AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by cable with the size of 30mm (diameter). For Area 2 machines' distribution, each machine was far from each other, thus when we install the energy meters, all the energy meters will be of separate installation and were also far from each other. (4) Area 3 was 2nd work shop with 18 machines 3-phase needed to be monitored. Each machine was powered by 1 circuit 3-phase. Circuit's rated current is 200A AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by cable with the size of 20mm (diameter). For Area 3 machines' distribution, each machine was close to each other. So all the energy meters could be of centralized installation in a DB cabinet. (5) Both 3 areas are covered by stable 4G signal. Meanwhile, WiFi or Ethernet communication was not available for these areas.   -Area Overview Sketch (To Protect the privacy of customer, only sketch available) 2.1 Devices Deployment Plan - Area 1: Area 1 was for main incoming circuits monitoring.

Acrel provides solutions for Beijing Winter Olympics venues

1. Overview The Beijing Winter Olympics will be grandly opened on February 4, 2022. This is a major landmark event at an important historical node in my country. It is an important opportunity to show the country's image, develop the country and inspire the national spirit. As the grand event draws nearer, as an important basic condition for hosting the Olympic Games, the construction of the venues for the Beijing Winter Olympics has always attracted much attention, and the stable and reliable operation of the power supply and distribution system of the venues is the top priority.The outdoor environment of the site is relatively harsh, and the temperature is as low as minus 20 °C. In order to ensure reliable power supply, each headquarters conducts power supply support capability tests according to the power supply duties, and tests the power supply tasks, main power supply and self-provided emergency power supply of each venue. Supply situation, operation of important loads, relay protection action, emergency response plan, spare parts, logistics support, etc. Acrel Electric provides solutions for intelligent monitoring of distribution boxes and environmental regulation in boxes for the Winter Olympics, and conducts online real-time management of power supply and power protection equipment such as cable branch boxes, ATS power boxes, and UPS power boxes. The edge computing gateway collects the electrical data, temperature and humidity, condensation, contact temperature and other data inside the indoor and outdoor power distribution cabinets and automatically adjusts them to achieve good operating conditions, realizing intelligent monitoring from the UPS to the low-voltage switch at the end of the venue for the Winter Olympics , to provide emergency support in a timely manner and improve the reliability of power supply. 2.System structure The system can be divided into three layers: the field device layer, the network communication layer and the platform management layer.Field device layer: including DTSD1352-4S2D-MK, DTSD1352-4S2D,ARTM-24,WHD46-33-C,WHD20R-22-C, ARTU-KJ8 and other signal acquisition equipment, used to collect electrical operation in indoor and outdoor distribution boxes Parameters, electrical contact temperature, ambient temperature and humidity in the box, condensation, smoke and other data, and can be automatically controlled by the built-in logic of the ANet-2E4SM intelligent gateway to adjust the temperature and humidity to maintain a good operating environment inside the distribution box.Network communication layer: including ANet-2E4SM intelligent gateway. The gateway actively collects the data of the field device layer equipment, and can perform protocol conversion, data storage, and upload the data to the local touch screen and the designated server port through the 4G network. Temperature and humidity control equipment. Platform management: a large platform for energy management in the Winter Olympics. 3.Solution The site mainly monitors and controls three types of distribution boxes, including cable branch boxes, ATS power supply automatic switching boxes and UPS power supply boxes, to ensure stable and normal operation of distribution boxes in severe cold environments. There are more than 500 distribution boxes of these three types included in remote monitoring, and the solutions for different distribution boxes are also slightly different.3.1Configure Device Inventory 3.2 Implement function Monitor the electrical parameters of the branch box circuit.When the temperature in the box is too low, push the alarm signal and start the heating.Cable connector over temperature alarm.Condensation detected to start heating and ventilation smoke alarm Socket power supply status detection.Adopt IEC60870-5-104 protocol to upload to Winter Olympic venue energy management platform through APN directional network. 3.3 Configure Device Inventory 3.4 Implement function When the temperature in the box is too low, push the alarm signal and start the heating Cable connector temperature collection, over temperature alarm.Condensation alarm is detected and heating ventilation is activated Smoke and temperature and humidity alarms.Adopt IEC60870-5-104 protocol to upload to Winter Olympic venue energy management platform through APN directional network 3.5Configure Device Inventory 3.6 Implement function When the temperature in the box is too low, push the alarm signal and start the heating Internal over temperature alarm Condensation heating Battery pack abnormal alarm Inverter failure alarm.Adopt IEC60870-5-104 protocol to upload to Winter Olympic venue energy management platform through APN directional network 4. On-site maintenance The opening of the Winter Olympics is imminent. In order to ensure the normal operation of the on-site power distribution system, Acrel arranged for engineers to maintain on-site and provide technical support for winning the tough battle of power protection for the 2022 Beijing Winter Olympics.Acrel has been deeply involved in intelligent power distribution for many years, and currently more than 14,000 solutions are running all over the country.
