With the constant promotion of technological integration of AI, blockchain, cloud computing and big data, driven by energy Internet, TBEA Sunoasis launches the smarter, more efficient and more reliable intelligent PV solution aiming to improve the popularity of clean energy.
With TS228KTL-HV large power string inverter as its core, the solution realizes integration of data from both the cloud and the plant terminal, ensuring more accurate and efficient transmission of information. In the meantime, this system solution is proposed to our clients based on the comprehensive analysis of the comprehensive scenarios of different topography, different system configuration and different environment for application.
Highly-efficient transmission of information
More accurate plant data and more convenient operation & maintenance
Quick and precise transmission of information is the basic function of digitization and intellectualization for plant. Inverter, as the key equipment to collect core data and control power of PV plant, has stricter requirements on the manner of correspondence. The entire series of TBEA Sunoasis’s string inverters is equipped with PLC correspondence function which adopts broadband OFDM technology to make data transmission faster and more secure. And as one of the important channels of inverter information transmission, PLC correspondence technology can not only saves costs, but also improves correspondence efficiency.
Based on such, TBEA Sunoasis’s Intelligent PV Solution also improves the “the operation & maintenance precision of PV plant”.
TBEA Sunoasis’s Intelligent PV Solution integrates the new generation IV curve testing technology which can improve the speed by 20% during scanning IV curves compared with ordinary method and IV data after scanning will be transmitted to the backend via high-speed PLC + optical ring network for IV curve analysis; taking advantage of the powerful computing capacity of TB-eCloud platform, it calculates and analyzes the feature parameters of string and can diagnose the malfunction type of IV curve from the database within the shortest time possible, providing clients with highly-accurate, visual and low-cost maintenance solution for plant.
Besides, TBEA Sunoasis’s TB-eCloud is able to provide intelligent solution for all-scenario new energy plants from the cloud to the plant terminal. It provides on the cloud terminal TB-eCloud PV plant intelligent operation & maintenance system and TB-eCloud mobile operation APP to help integrate resources.
The plant terminal is mainly responsible for monitoring, managing and maintaining different equipment of the plant. It provides intelligent PV monitoring system and intelligent PV analysis system for the plant terminal and by analyzing plant index, health index and equipment operations, it generates visual reports to provide supports for decision-making; alarms are pushed in a timely manner and plant data can be accessed anytime anywhere.
Precise disturbance to find the best sunlight
Synergy is the precise expression of efficient cooperation. Synergy between equipment such as components, inverter, communication box and transformer in the PV plant generates constant green energy. The PV component, which generates “power” directly in the generation unit, has become intelligent and can rotate different components controlled by tracking support and is the “enabler” of power.
Traditional tracker follows the classic astronomical algorithm to rotate slowly at certain time, amount and angle; however, as the weather changes so fast, it may have already missed many chances to contact with the sun.
TBEA Sunoasis shares the data between inverter, tracking support, communication box and monitoring system of PV area and based on efficient data exchange, the intelligent inverter integrates the communication of tracking supports, matches the branch MPPT with connected tracking device and uses dynamic fuzzy algorithm to positively adjust the tracking devices on corresponding branch to ensure precise control and avoid coarse intelligent coordination and control.
Intelligent inverter on one hand uses the internal sophisticated AI system to conduct close-ring adjustment and on the other hand coordinates the monitoring system in the PV area to be aware of the plant’s current and latest sun exposure information and the ultra-short power forecast to fully release the potential of components under each tracking device in every branch, realize maximum power output of every branch, each inverter and every matrix and further refine the benefits of plant.
From adapting to the grid to support the grid
In the power system, with the increasing share of grid-connection of new energy power, especially PV power, the issue with high-proportion PV power grid-connection is becoming outstanding, which mainly refers to the weak grid features. Weak grid is prone to cause unstable voltage, unstable frequency, resonance and other issues. This challenge can’t be effectively addressed simply by adapting to the grid; we need to change the mentality from adapting to the grid to supporting the grid, from passive to active, by fully improving the grid-connection capability of PV inverter to realize friendly connection.
TBEA Sunoasis takes advantage of TB-eCLoud platform’s ability in calculation and storage of big database and based on the years of experiences in system integration, conducts system modeling for multiple scenarios for grid-connection and plant design before importing. Then by the strong leaning ability of TB-eCloud platform, it constantly follows the operation of PV plant after grid-connection to constantly train and optimize system modeling and grid-connection models; it customizes for different locations and grid-connection features under different scenarios to provide guiding for grid-connection of inverter.
By the guiding of cloud platform, the inverter dynamically adjusts its parameters to fit the grid, for example, under weak grid, it can adopt resistance reconstruction algorithm to help inverter establish stable environment for grid-connection and support the stable operation of grid. By integration and constant learning between cloud platform and inverter, it realizes customization and friendly connection.
TBEA Sunoasis will continue upholding the concept of promoting innovative development based on renewable energy and helping clients achieve more value by technical innovation and upgrade. Based on TS228KTL-HV large power string inverter, TBEA Sunoasis builds the “intelligent PV solution” which integrates many intelligent technologies, helps client increase plant gain and is the definite choice of plant system solution in the age of parity/competition.
