PVTIME - With the advent of the digital era, AI, blockchain, cloud
computing, and other technologies are widely used in more and more fields.
As a multiyear TeraWatt sponsor of the SNEC International Photovoltaic Power Generation and Smart Energy Exhibition & Conference, TBEA Xinjiang New Energy Co., Ltd. (hereinafter referred to as "TBEA New Energy") exhibited its 1500V string and central intelligent PV power generating solutions for the era of grid parity, power quality solutions, intelligent microgrid solutions, TB-eCloud Intelligent Operation and Maintenance solution which incorporates AI and cloud computing technology, and a new generation of intelligent products such as TS228KTL-HV string inverters, energy storage converters PCS, and TC3125KF centralized inverters at the 14th SNEC last month.

In the photovoltaic industry, many companies are trying to improve power
generation efficiency by applying digital technologies such as AI and cloud
computing to equipment such as the inverter and
the module individually. However, TBEA New Energy’s approach to AI technology
is completely different.
“The AI application of TBEA New Energy does not focus on a
certain device or individual link, but on the entire power station, the entire
region, and the entire group.” Xu Bofeng, Deputy
General Manager of TBEA New Energy, said in an interview with a reporter from PVTIME.
“Currently, intelligent operation and maintenance in the market is more
inclined to standardize the operation and maintenance specifications of power
stations, and intelligentize the inspection, maintenance, safety, quality
supervision, and other aspects of an operation, while the intelligent operation
and maintenance of TBEA New Energy is to integrate and open up the relationships
between people, people and equipment, equipment and equipment, rather than just
"Take dust accumulation in power stations as an example. The accumulation
of dust on photovoltaic panels has a definite affect the its power generation efficiency.
According to common sense, if there is dust accumulation, it must be cleaned. However,
if you learn in advance through the weather forecast system in the operation
and maintenance platform that there will be an 80% chance of heavy rain the
next day, the cleaning work should be properly delayed. Conversely, even if it
does not rain the next day, you must still consider when and how the panels
should be cleaned.” Xu Bofeng said. “If the dust accumulation at the power
station is a "point", then the power station is a "line",
and all power stations in the region are on a "plane". What TBEA New
Energy is doing with AI technology is connecting the "points" to
"lines", then connecting the "lines" to "planes",
and reducing the electricity cost per kilowatt-hour of the power stations with
our lifecycle operation and maintenance method.” Xu added.
stations have different characteristics, and in the face of complex development
environments and power generation systems, progressively declining electricity
prices, and increasingly accessible data and information, the traditional
design ideology cannot meet the complex design requirements of these modern
Combining its 20-years of experience in the development, construction, and operation maintenance in photovoltaic, wind power, power transmission and transformation projects, with its industry status and foresight, TBEA New Energy has invested a lot of resources into the creation of a digital system suitable for the entire lifecycle of a project.
This digital system,
capable of governing 9 aspects including a project’s macro site selection,
resource evaluation, micro site selection, economic evaluation, project design,
project construction, project construction management, project O&M, and
project optimization and improvement, has one interface, three supports, four
sections, and five platforms. The one interface refers to TB-eCloud, the new
energy industrial internet platform which supports new energy cooperation,
co-construction, and information exchange. It is also the foundation to IoT,
data analysis, capability sharing, and applications development. The three supports serve as a key
mechanism for digitalization and enables the construction of a digital culture,
recruitment of digital talents, and improved digital organization. The four
sectors covered by the SaaS system include the digital wind/photoelectric field
operation, intelligent manufacturing, engineering services, and integrated
energy management. Lastly, the five platforms refer to digital engineering
design platform, digital engineering service platform, intelligent electric
field platform, integrated energy platform, and intelligent equipment
Ensuring power station
revenue generation with powerful intelligent system support and dual terminal
understood that TBEA New Energy’s system has already been fully applied in the
resource evaluation and design process of multiple photovoltaic and wind power
projects. A TBEA New Energy intelligent photovoltaic solution based on this system,
with the TS228KTL-HV high-power string inverter at the core, can achieve dual
terminal data integration from the cloud to the station. The cloud provides
TB-eCloud photovoltaic power plants the intelligent O&M system as well as
the TB-eCloud mobile operation APP in order to facilitate the integration of
resources. On the station’s end, an intelligent photovoltaic monitoring system
and an intelligent photovoltaic analysis system provide analysis of the power
station’s health, equipment, operation, and generates visual reports which can
provide strong support for decision-making at all levels.
New Energy intelligent photovoltaic solution incorporates a new generation of
IV curve detection technology which can improve the scanning speed by 20% compared
to conventional scanning method during the IV curve scanning stage. The scanned
IV data is transmitted to the backend through the high-speed PLC + optical ring
network for IV Curve analysis. Then, the powerful computing capability of the
TB-eCloud platform calculates and analyzes the parameters of the string, and
can diagnose the fault type of the IV curve from the database in the shortest
time, and finally provide the clients with a visual, highly accurate, low-cost maintenance
solution for the power station.
On top of
achieving precise operation and maintenance, the solution also opens up the
data channel between the inverter, tracking bracket, communication box, and
photovoltaic zone monitoring system, integrating the tracking bracket
communication with the intelligent inverter, and matching the branch to the MPPT.
Corresponding to the connected tracker, a dynamic ‘fuzzy’ algorithm is used to
actively adjust the tracker of the corresponding branch in order to ensure precise
control and avoid issues with coordination and control. The maximum output of
power generation of each circuit, each inverter, and each square array then subsequently
increases the power plant’s revenue generation.
Intelligent channel trailblazing leads to performance
construction of a digital system platform has opened up a real-time channel for
the sharing of power station application data and information across various
industry sectors, and also helped TBEA New Energy's performance soar. According to
statistics, the global shipments of TBEA New Energy’s inverters have exceeded
30GW, and the number of wind power and photovoltaic power plants has surpassed
5,000. In the “Top 500 Global New Energy Companies in
2019”, TBEA New Energy jumped by 8 places to the 89th place.
TBEA’s 20th year in the field of new energy, and is also an
important year strategically for TBEA New Energy. Xu Bofeng revealed that in
the coming days, in order to adapt to the changing trends of the times, the
company will work with all partners in the ecosystem to innovate business
cooperation models, and jointly explore areas such as green finance, energy
trading, energy efficiency management, intelligent power plants, and intelligent
energy equipment, so as to lead the wind and photovoltaic industries into a new
era of grid parity!
