How complex is the production process of a smart energy meter? From incoming materials to logistics, there are 34 processes. What if it was a smart energy meter with a low-carbon goal?
In the green and low-carbon advanced technology demonstration base, located in Yueqing City, Wenzhou, Zhejiang Province, CHINT Measurement Industrial Park, we followed an order for a smart electric energy meter and experienced a low-carbon journey.
The Spring Festival is approaching, and the pressure on orders and shipments in the park is huge. An overseas customer requested 417,000 pieces of smart energy meters to be delivered within 15 days.
When the system receives the order instruction, it first triggers the integrated dispatching management system of "source-grid-load-storage", the brain of carbon emission control in the park.
The integration of "source, grid, load and storage" is the "big easter egg" buried in the park, corresponding to smart energy management, visual power distribution network, fine load management, and efficient charging and energy storage. "After they are successfully networked, every bit of energy change in the park will be accurately sensed and calculated, and eventually become the 'brain' of green production. Gu Zhangping, general manager of Zhejiang Zhengtai Instrument Co., Ltd., made an analogy, "Just like when we receive a task, we must think about it before starting construction, how to complete it quickly and labor-saving." That's what this management system does. ”
But systems are not human, and their thinking depends on the data collected from every link.
On the smart watt-hour meter production line, each machine is equipped with a "small white box" - a carbon footprint IoT collection device, which is systematically reporting the energy consumption of each process and the carbon emissions of each product in real time. Only equipment in good condition and low energy consumption per unit is eligible to take orders.
"It's like a physical education teacher selecting a student with better athletic ability to represent the class in the sports day. The reporter replied.
"Right idea! You can be our system strategist. Gu Zhangping took over the conversation with a smile, and the system has already had evaluation results: the data shows that among the 12 production lines in the smart electric energy meter production workshop, the No. 6, No. 7, and No. 11 production lines have low energy consumption, and the system matches them to undertake 70% more production tasks than other production lines. It seems that in the world of machines, "those who can work more" are also applicable.
Being eligible to receive orders does not mean that work will start immediately. The energy system of the park is laid out with a variety of energy systems such as photovoltaic, energy storage, ice and cold storage, etc., whether to call the 1 megawatt photovoltaic power generation laid on the roof, or to start the energy storage equipment? At this moment, whether the external power supply is a "peak" or "valley", and even whether the electricity load of the administrative building needs to make way for production, etc., must be calculated one by one.
"It sounds complicated, but it doesn't take more than a few seconds. Gu Zhangping said that the smart electric energy meter order was "running the system" to generate a production plan: 12 production lines were concentrated at 8 o'clock to 22 o'clock, and the production capacity was concentrated within 15 days with 1.5 times the usual production capacity. On the other hand, the energy-saving assessment has also been released: photovoltaic, valley power, and energy storage are released alternately, and the total energy consumption is reduced by 08,500 kWh compared with that when there is no adjustment, and carbon emissions are reduced by 8.47 tons, which is equivalent to saving 0.6 days of energy consumption for the entire park. "This is just an order to reduce consumption and carbon emissions, and what is saved over time is profits, and what is improved is the competitiveness of enterprises. Gu Zhangping said that the carbon emission of a smart electric energy meter is 50.15 kilograms (carbon dioxide equivalent), which can reduce carbon emissions by 8% compared with traditional production. By closely combining carbon reduction and production, low-carbon targets can be translated into new productivity.
In fact, our low-carbon experience starts from the first step into the campus. There are 1,681 sensors installed inside and outside the building, and our every move has an impact on the energy consumption plan of the park. These data are supported by the HPLC (carrier technology) + Bluetooth dual-mode communication technology independently developed and pioneered by the CHINT team, so that the near-zero carbon architecture of "source-network-load-storage" can be applied. Although the park has only been in operation for four months, the green and economic effects it has brought have already made local enterprises "red". Because the software and hardware of the whole system are manufactured by CHINT, this makes the Tao program of the marketing department of CHINT instrument very busy.
As far away as Inner Mongolia, CHINT's partners have begun to replicate the system in the industrial park, which is expected to be completed and put into use in June 2024. Near Yueqing, some of the newly built parks around it have reached energy management cooperation with the measurement park. Not long ago, more than 400 CHINT dealers from all over the world came to observe the power departments of their countries and regions. "Every time we go to the part of the integration of source, grid, load and storage, the observation team can't move. Tao Gang still remembers the scene vividly, "It is foreseeable that 2024 will be a busy work year." ”
