Power -saving power -limited photovoltaic energy storage guarantee office electricity and key projects are non -stop production

Red Star News Network (Reporter Li Huiying) On August 24, it was reported that in recent days, Chengdu has continued to have high temperatures, and power supply sounds the electricity limit. Everyone is facing the dual "baking" test of high temperature and electricity limit. The Shedutagawa Kaikawa Electric Industrial Park, located in Shuangliu District, Chengdu, is produced as usual in the sheet metal workshop and assembly workshop. The robot is waving the side plate of the robotic arm machining power distribution cabinet. At this time, the electricity consumption of the park comes from the photovoltaic power generation component of the roof of the plant.

15,000 square meters of photovoltaic power generation saves about 800,000 yuan per year

"In response to the government's call. At present, we rely entirely on their own equipment and use emergency generators and roof photovoltaic power generation to ensure the safety of security electricity and employee dormitory and key projects of key projects. According to Liu Shixu, the dean of the Institute of Research, said, "The roof of the park is 15,000 square meters and can be generated about 5,000 degrees per day." Relying on the roof of the park, photovoltaic power generation can solve the energy of about 1/3 of the park, reducing the peak load of about 1/2 during the day during the day Essence

Chuankai Electric Co., Ltd. is the largest electrical switch R & D and production base in the Southwest. It is mainly engaged in the research and development, design, production and sales of power transmission and distribution equipment. When the company launched the construction of the new park in 2016, it was positioned as a green low -carbon park. Create smart application scenarios and other smart application scenarios such as photovoltaic, energy storage, charging and discharge piles, and water storage cold air conditioning systems to promote energy conservation and consumption reduction. The park is 100,000 square meters, the pilot roof photovoltaic is 15,000 square meters, and the investment is 12 million yuan. All of them are equipped with cadmium cadmium film power generation components. Liu Shixu further introduced that there are two ways to transform solar energy into electrical energy: one is a centralized photovoltaic power station, mostly distributed in Gobi or fish ponds with good light resources; the other is distributed, photovoltaic power generation The component layout is on the roof or curtain wall of the user. Compared with centralized energy, distributed energy does not occupy additional land resources, which can reduce the cost of transmission and distribution and achieve local production and utilization. "We choose the cadmium cadmium film power generation component more advantages in the weak light environment, and it is more suitable for areas such as Chengdu with less light time."

Liu Shixu is still a account. According to the current average electrical cost of photovoltaic power stations, the photovoltaic return of the Chengdu region is about 10 years in this cycle. The remaining 30-50 years will continue to bring benefits to enterprises. The parking of 15,000 square meters of roof photovoltaic, 1.4 million kilowatts per year, saved about 800,000 yuan per year at the current electricity price. It not only reduces the cost of corporate costs, but also reduces the energy consumption of the national network with electricity, becoming a useful supplement to the State Grid.

Large "power bank" guarantee office electricity

The production in the workshop of the Chuankai Park has not stopped, and the computers of the office area of ​​the low -carbon technology demonstration area of ​​Zhongjian Binhu Design Headquarters of Xinglong Lake are also running normally. The "electricity" here also relies on the roof solar photovoltaic power generation. "The lighting and computer power consumption of this office area, as well as basement lighting and charging, all come from our distributed photovoltaic power generation and basement energy storage rooms to complete the entire set of power delivery." introduce.

The photovoltaic board is distributed on the top of the office building. The system can monitor the power generation and power consumption in real time. This is also the first building in the western region to use 'optical storage straightness' technology. "It is understood that the optical storage straight (PEDF) technology is to apply solar photovoltaic (Photovoltaic) in the construction field (Photovoltaic) Energy Storage, Direct Current, and Flexibility are abbreviated for abbreviation. The system is usually powered by photovoltaic, and the remaining photovoltaic can be stored in the basement energy storage room. When power outage in the municipal electricity, the power storage system can also be continuously powered by photovoltaic and energy storage.

As the first near -zero -carbon building in Chengdu, the power -saving measures here are more than that. The entire design headquarters conducted analog analysis of the large space lighting problem when designing. Setting the lighting patio in the most favorable area to enable 87%of functional rooms to meet natural lighting standards, so as to reduce the light opening of the day; use the roof garden to set up optical catheter catheters. , Guide natural light into the room to further reduce lighting electricity. At the same time, the inductive module of the "station lighting DALI control system" can sense the activity of the regional personnel, cooperate with the illuminance induction, and perform the switch and brightness adjustment of the lamps to avoid the light of the office area's empty light.

In office power, air conditioners are a large energy consumption. In addition to creating roof gardens and vertical greening, cooling down the building, the "jacket" of the building -the building curtain wall also uses a special material glass. The three silver double -cavity of the gel glass curtain wall has better thermal insulation and thermal insulation performance. "Compared to the conventional glass curtain wall, the heat of the summer in the summer can be reduced by 45%, which saves 7%of the energy consumption of air -conditioning in summer. For this building, it can save 80,000 degrees of electricity because of this technology." China Construction China Construction. Yang Zhengwu, deputy director of the Double Carbon Center of Binhu Design Headquarters.

On the window, the designer also spent a lot of thoughts -the "meteorological tracking technology self -control skylight" adopted by the building can be automatically turned on according to the sensor linkage, plus the louver can be opened, which increases the natural ventilation area.In the design, the CFD (calculating fluid dynamics) simulates the outdoor air environment and makes full use of natural ventilation; it is also experimenting with the "pre -cold ventilation technology" in the local experiment.EssenceEven in the case of such hot weather and not turning on the air conditioner, the physical sensation of the reporter in the office area is more comfortable.▲ Zhongjian Binhu Design Headquarters Roof Light Board

It is understood that the design headquarters of Zhongjian Binhu adopts more than 40 new green low-carbon new technology, which is a standard of 120 kWh/square meters per year from the average annual energy consumption of the general office building in Chengdu, which is reduced to 40-50 kWh/square meter.It saves 1.86 million kWh, about 1.5 million yuan, and reduces carbon emissions by about 1,027 tons annually.
