Analysis of Five Problems in Smart Grid and Substation Design

Arthur ˙Savar, Bentley's vice president of global power business, is a power cow. He has worked hard in the global power industry for more than 30 years.

Savar graduated from the University of Wisconsin, majoring in electrical engineering. After graduating, he worked for Schneider and other power companies. He later founded his own company, ECTI, and developed the promis.e, an electrical design software system that is well-known in the global power engineering design industry. Acquired by Bentley as the vice president of the global power business of Bentley.

He came to Beijing during the two sessions this year and he came to China for the 31st time. The author and he conducted a lively dialogue on the three-dimensional design of smart grids and substations. He talked about the five major challenges and solutions for the design of smart grids and substations:

One, smart grid is every device in the network must be intelligent

Second, the smart grid is full life cycle intelligence, there can be no broken phone phenomenon

Third, non-smart grid can use point cloud technology transformation, three-year cost recovery

Fourth, the choice of smart grid three-dimensional design technology to consider two major factors

V. The key to the success or failure of smart grid design lies in people

Author: As a smart grid network in China 2.0 is a hot topic. How do you understand the smart grid and its design principles?

Savard: The smart grid refers to the equipment and communication network of the electric infrastructure that carries intelligent information. It can regulate itself according to the needs and other factors. As China's demand for electricity grows, the demand for smart grids is urgent, because smart grids can deliver electricity to where it is most needed. The grid needs to be regulated, so it also needs its own regulation.

What we should do most is to apply intelligent design techniques to design smart grids from the source. For example, in the design of substations, not only substations should be smart, but also every device on the substation must be intelligent, that is to say, each device should be accompanied with key data for driving intelligence.

Reporter: The smart grid comes from design, but it does not stop at the design. How can smart design better support the smart operation of the smart grid throughout its life cycle?

Savard: Intelligence comes not only from design, but also from subsequent construction, operation and maintenance, so that we can deliver data from the stage of intelligent design to construction and operation. The biggest challenge we see is the transfer of design data from the engineer's personal computer to the full life cycle of the infrastructure network. We have a phone call in the United States that is broken. It means that when design engineers use traditional methods to transfer data from engineering drawings and data sheets, they are destined to lose something while they are on the way.
