Under the tide of the era of carbon emission reduction, the green race is sweeping across the country, and the former "coal sea granary" is actively chasing the "new". Up to now, Fengcheng's first 100 MW photovoltaic power generation project using TBEA's new energy smart photovoltaic solution has been running for many months, and Fengcheng smart photovoltaic benchmark power station is well-known.
Frozen rice sugar, selenium-rich rice... A national top 100 counties and cities are about to come out! In the past, the name of "coal sea granary" was well-known throughout the country.
Located in the middle and lower reaches of Jiangxi Province, Fengcheng City in the middle and lower reaches of the Ganjiang River controls the important lifeblood of national grain production, and the energy engine that drives this grain "giant ship" forward is none other than thermal power generation, and the Fengcheng Mining Bureau, a large-scale unified coal mine in the country, and the Fengcheng Power Plant, the largest thermal power plant in Jiangnan, are all located here.
100 million kWh = 36,000 tons of standard coal saved per year
Fengcheng's first 100 MW photovoltaic power generation project started construction on October 13, 2020, took 77 days to complete, and has been running efficiently for 8 months. According to the design, after the completion of the power station, the average annual on-grid electricity consumption exceeds 100 million kWh, which can save 36,000 tons of standard coal, which is of great significance for promoting the energy transformation and green development of fengcheng, the "coal capital".
The high power generation capacity of the power station is inseparable from the "escort" of efficient equipment. It is reported that after the multi-party comparison of the project owners, the Fengcheng project finally chose the smart photovoltaic solution of TBEA New Energy. Compared with the traditional inverter, TBEA New Energy Intelligent Photovoltaic String Inverter 12-channel MPPT supports the maximum MPPT current of 40A, which effectively reduces the power generation impact caused by the series parallel mismatch, keeps the string inverter in the best power generation state, and supports 1.8 times the capacity ratio, reducing the investment cost of the power station, thereby maximizing the benefits of the photovoltaic power station.
In addition, in view of the fact that the power station is located in the gray field of the first phase of the power plant, with more dust and harsh outdoor environment, TBEA New Energy TS228KTL-HV string inverter protection level reaches IP66, anti-corrosion grade C5, which can not only adapt to high dust environment, but also adapt to extreme environments such as high temperature, high humidity, high salt spray, etc., matching all-weather PID protection patented technology, multi-in-one guarantee component power generation efficiency, safe and reliable, and also provides reliable guarantee for the long-term stable operation of the project.
Smart photovoltaic benchmark power station
At present, the photovoltaic industry not only undertakes the responsibility of implementing the "double carbon" goal, but also is the commanding heights of global advanced industry competition in the future, further improving the quality and efficiency of the development of China's photovoltaic industry, and realizing the intelligent upgrading and application of photovoltaics has become the top-level strategic goal. Since 2018, six major departments, including the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, and the Energy Bureau, have jointly issued the "Smart Photovoltaic Industry Development Action Plan" to lead the intelligent transformation of the photovoltaic industry.
As far as photovoltaic power plants are concerned, the culmination of the level of intelligence is nothing more than operation and maintenance. For the possible failure of photovoltaic modules in the operation of the power station, the manual inspection method was used in the past, which not only could not fully understand the status of the components, but also had a low fault recognition rate, which increased the difficulty and cost of manual detection in the face of the complex environment of the photovoltaic power station site.
In order to solve this problem, TBEA's new energy photovoltaic solution is equipped with the intelligent monitoring function of IV curve, which can achieve a class I defect recognition rate of 95%, a class II defect recognition rate of 90%, and 14 fault types. In addition, combined with the TB-eCloud cloud platform to achieve the fully digital intelligent operation and maintenance of the power station, the operation and maintenance efficiency is increased by 50%, the cost of kWh is reduced by 2%, and the operation and maintenance management of the refined, collectivized and full life cycle of the power station is more efficient, convenient and intelligent.
What is more worthy of attention is that the construction of new power systems has become one of the core strategies for the implementation of the "double carbon" goal in China, but the volatility and intermittentness of new energy sources such as photovoltaics have brought great challenges to the stability of the power grid, so photovoltaic power plants under the soaring scale need to actively support the adaptation of the grid. In this regard, TBEA's new energy string inverter TS228KTL-HV passed the SCR 1.2 weak network working condition test of the State Grid Electric Power Research Institute to meet the continuous high and low penetration requirements under the SCR1.2 working conditions, ensure that the equipment is stable and grid-connected in the case of extremely weak power grid, and more intelligently adapt to the power grid. It can be expected that under the benchmarking effect of smart photovoltaic power plants, Fengcheng's photovoltaic industry will press the "fast-forward button", and outside the granary and coal sea, photovoltaics may become the next flash label of Jinfengcheng. Not only that, with Fengcheng as the starting point, TBEA New Energy will also continue to innovate with the goal of "double carbon", empower green development with technology, and provide better smart photovoltaic solutions for more users.
