Recently, the 7th "Seminar on New Energy Power Station Operation and Maintenance and After-sales Service Market" was held in Beijing. Practice" as the title, deeply analyzed the future vision and realization path of smart electric field construction, and put forward the Goldwind plan for the construction of "black lamp electric field".

Under the guidance of the "Double Carbon" strategy, the "grid grid parity" policy has been fully implemented, and the marketization of power trading has continued to advance. New energy operators are facing major challenges in large-scale asset management while focusing on cost control and income risks.

In this context, using scientific and technological innovation as the engine to promote digital transformation and intelligent upgrade, to achieve cost reduction and efficiency increase has become the underlying driving force for the construction of smart electric fields.

At present, most power generation enterprises have realized the integration of centralized control and production management, and realized "fewer people on duty". In the next five years, the ideal goal of new energy farms is to achieve "unattended operation", which will be a turning point in the intelligent management of new energy farms, that is, from the original "people-oriented" to "machine-based".

Goldwind defines "unattended" electric field as "black light electric field", that is to realize centralized control operation on duty and on-site "unattended".

To build a "black lamp electric field", the following three key technologies and core capabilities will become breakthroughs.

Customized design is the core competence

"The core of the intelligent construction of the station is not the deployment and stacking of various high-tech equipment, but the integration of digital technology and the actual business of the station through the customized design capabilities of intelligent transformation according to the actual management and operation scenarios of the station. Deep integration will promote the improvement of operation and management efficiency", Ma Hui pointed out.

The intelligent upgrade project of 100MWp centralized photovoltaic power station completed by Goldwind Technology and an energy central enterprise is a typical representative of the combination of automatic inspection technology and station business.

Photovoltaic power plant field group monitoring

In the past, to complete an inspection of 320,000 photovoltaic modules in the whole station, four employees were required to work for 60 days; relying on the safety management plan of "on-site navigation + personnel tracking", after using drone inspections, only two inspections are required It can be completed in two days with two drones. Based on six inspections per year, more than 1,400 man-days can be saved. At the same time, the fault detection rate has reached over 95%, and the fire hazard has been minimized.

Scenario-based AI technology application is the key

The power industry is a knowledge-intensive industry that requires a large number of professionals in operation and maintenance. However, the industry is facing the pain point of young and inexperienced on-site personnel. The traditional "master with apprentice" or centralized off-production training mode is time-consuming and laborious, which affects the improvement of operation and maintenance efficiency.

The "smart maintenance" technology based on the scene-based AI algorithm model allows on-site personnel to call the "fault library" through a small program or mobile APP, and then obtain the corresponding fault solution, realizing the transformation from "word of mouth" to "finding out by picture" "The evolution of the system reduces training costs and trial-and-error costs, and achieves intelligent operation and maintenance efficiency.

In 2020, in response to the substantial increase in the grid-connected capacity of a central energy enterprise in the northwest region, the "smart maintenance" solution provided by Goldwind effectively reduced the manpower consumption in dispatching orders, preparing spare parts, preparing tools and equipment, and overhauling, and facilitated troubleshooting. Efficiency improvement. According to the 2021 year-end accounting, while the asset scale is expanding, Goldwind's "smart maintenance" has saved customers more than one million yuan in operation and maintenance costs throughout the year.

"Smart center" is the underlying support

In the future, the characteristics of smart electric fields will be manifested in the diversification of business scenarios such as "window, wind and water storage networks", the popularization of smart terminals such as drones, inspection robots, and cameras, and the integration of platforms such as the Internet of Things, big data, and intelligent algorithms. and the refinement of operation management.

Especially after the electricity market transaction is liberalized, the granularity of resource allocation has changed from the previous "weekly level" to "hourly level" or even "minute level". The traditional asset management model that relies on personnel experience has encountered new challenges.

Smart Electric Field Topology

How to organically integrate these devices and systems so that they can complement each other without conflicting, the role of the "smart scheduling management center" is particularly important.

As the smart brain of all station business, the "Smart Scheduling Management Center" highly integrates information such as real-time production data, production activity data, market windows, operation windows, maintenance windows, and business intelligence, and outputs optimal operation scheduling strategies to gradually realize The goal is to minimize downtime hours, optimize power generation, minimize operating costs, and maximize revenue from electricity sales.

Digitization, informatization, and intelligence are the core elements of future energy development. Facing the bright future of energy digitalization, Goldwind is committed to giving full play to its own technological advantages and promoting the industry to embrace the changes of the times. Goldwind Technology will become a promoter of integrated co-creation and ecological openness, and gather strong synergy with all parties in the industry chain to jointly build an intelligent ecology and win-win digital future.
