Project Overview
Changshu Institute of Technology is located in Changshu, Suzhou – a national historical and cultural city as well as an international garden city, renowned for its rich cultural heritage and beautiful landscapes. It is a public full-time general undergraduate institution co-built by the province and the city. The predecessor of the university was Suzhou Normal College, founded in 1958. In 1989, Suzhou Normal College merged with Changshu Vocational University to establish Changshu Junior College. In 2001, Jiangsu Provincial Population School was incorporated into it. In 2004, with the approval of the Ministry of Education, it was upgraded to an undergraduate institution and renamed Changshu Institute of Technology. The university currently has two campuses, Donghu and Dongnan, covering an area of over 1,800 mu (about 120 hectares) with a building area of more than 600,000 square meters.
This project is designed to provide the client with an energy consumption platform for building a 4 levels metering system from the substation to each classroom, including the requirements for a photovoltaic power generation monitoring platform.
Project Requirements
The entire project covers two campuses: the Southeast Campus has 5 substations and 13 buildings, while the East Lake Campus has 6 substations and 12 buildings. The Southeast Campus has a photovoltaic capacity of 3MW, and the East Lake Campus has a photovoltaic capacity of 5MW. In total, there are 2750 meters. The requirements are as follows:
Realize centralized energy management of the two campuses.
Power distribution levels from substations to each building.
Connect renewable sources to meet the requirements of green buildings.
Conduct an analysis of energy rationality based on the use of utility and renewable energy.
Complete the operation and maintenance management of the school's power distribution, photovoltaics, and safety.
Project Solution
• Substation / floor distribution box: install ADW300, collected by ANET gateway via wired RS-485, then the gateway access the school's local area network nearby.
• Classroom lighting and air - conditioning PZ30 box: Install 1P and 3P energy sensors, which transmit signals through LORA to ARCM60-MS-LW/M2(LR)U gateway and then to LORAWAN industrial gateway.
• Access the virtual server and system platform through the school's VPN.
• Deploy EMS (power monitoring, electrical energy management, energy consumption monitoring, operation and maintenance management).
The monitoring module includes：
• 708 pcs ADW300W/C energy meter
• 1000 pcs ARCM620(LR)-1P-W/T1 energy sensor
• 855 pcs ARCM620(LR)-3P-W/T3 energy sensor
• 46 pcs ADW300/C energy meter
• 180 pcs ARCM60-MS-LW/M2(LR)U gateway
• 9 pcs LORAWAN industrial gateway
43 pcs ANET gateway
