First of all

we need to construct an Artificial Intelligence system to perform two tasks:

AI system

1.Create any possible design of wind turbine based on certain constraints we applied to the system. These constraints are prepared from the conceptual design of the wind turbine, production capability, physical limitation and material properties. We called it computer generated modelling (CGM). 2.The system will combine some performance indicators (PI) and the information of the model being generated to predict the next candidate which will have high performance indicators.

Using this process loop

we are able to make use of the Artificial Intelligence to self-improve the wind turbine without any human involvement.

Simulation

At this moment, the system is not able to understand the theory of aerodynamic so it needs help from external tools to provide the performance indicators. Here is where the simulation is applied. We are using Xflow from Dassault Systèmes to understand the aerodynamic behavior of the wind turbine and create some performance indicators which will be input to our artificial intelligence system. One of the performance indicators is power coefficient (Cp). The power of the wind turbine can be calculated by using rotational speed and torque. In a range of rotational speed, the ratio between mechanical power to wind power will be varied. In general, the ratio will be lower in slow rotational and high rotational speed. Then, we can see a maximum ratio happening in one particular rotational speed in between two extreme cases. We call it the power coefficient.

Xflow

At the end of the process loop inside Artificial Intelligence system, we will come up the final design, which will be sent to production team to create the overall supportive structure and incorporate into the product. Finally, Xflow will be used to study and minimize the performance impact of supporting structure.

Our Project

HKCEC is out first installation site in Hong Kong. Three units of WA62C WindArc Outdoor Street Lights were installed at the Expo Drive entrance in August 2015. The units provide evening lighting for the area.

To enhance the purchasing, installing and maintenance experience of our clients, ATAL Engineering Group became Robin energy Limited's authorised dealer in Hong Kong. The  WA62C WindArc Outdoor Street Light unit installed at the outdoor leisure area on the 5/F of Landmark North is the first collaboration between Robin Energy Limited and ATAL Engineering Group. The client was first concerned about the low power output due to the insufficient wind resource in the installation site. However, with the patented magnetic resistance free generator and the unique wind blade design, electricity is efficiently generated even in low wind speeds. This has been a breakthrough on the hypothesis of wind energy can only be generated in sufficient and high wind resource sites in the past.

In 2017, Electrical and Mechanical Services Department had a lighting units replacement project at the EMSD Headquarters main entrance, in which the replaced lighting units shall be energy efficient and environmental friendly. Three units of WA62C WindArc Outdoor Street Lights were thus installed for this project as our lighting systems fit the needs and requirements of EMSD. After running this project for a year, EMSD has shown satisfaction to our products and services and has given us a letter of appreciation to ensure the product quality.

As HACTL is located in Chak Lap Kok, the wind resource is abundant and sufficient for wind energy generation. Therefore, a WA80F WindArc Outdoor Street Light unit was installed alongside the road.

This project is located at a Community Green Station in Tsing Yi organised by Environmental Protection Department. The Community Green Station scheme was started in 2014 by EPD to promote the environmental awareness and education of the neighourhood and to improve the recycling of different materials. The installed unit not only provide practical lighting but also educates the citizens of the importance of renewable energy usage.

The Victoria Skye, as the landmark of Kai Tak development area, is nearby several shopping malls and private properties. Installation of street lights in Victoria Skye helps provide lighting systems for local residential buildings which brings environmental elements for economic development.
