At the 1,000-kilovolt ultra-high voltage Huainan Station's GIS test site, staff members from State Grid Anhui Electric Power's power science research institute carried out various tasks with the help of an ultra-high voltage (UHV) large-scale test management app.

They effectively checked the test plan and equipment, and assigned test tasks and safety precautions to the team members. With the support of the app, every step was processed in order.

By fully utilizing existing digital tools, the staff members of the institute integrated the business mid-end data and merged digital instruments to create the UHV large-scale test management platform. By detailing various test processes such as withstand voltage tests and start-up and commissioning tests, a standardized operational process system able to realize overall segmented control and local lean management was also set up.

The overall test process was divided into four stages: preparation, connection, pressurization and disconnection, with each stage logically locked in sequence to ensure a standardized and informatized complex test process.

With the support of the power grid's equipment information base, the precise retrieval and intelligent push of technical standards and operation instruction cards were achieved, allowing test personnel to access relevant data at any time during the test process, ensuring that the test operation is well-founded.

The UHV large-scale test management platform has been made into an app based on the iStateGrid's framework in a bid to promote the digital instrument applications and achieve the efficient and secure interaction of test data both internally and externally.

With advanced data processing and communication technology, traditional test instruments were digitized. Through wireless communication methods such as Bluetooth and Wi-Fi, computers, mobile terminals, test instruments were interconnected to achieve automatic data collection, processing and internal and external network interaction, providing a new model of fully digitalized management for test operations.

Based on business data, the platform regularly conducts multidimensional evaluations of operational quality and effectiveness, consolidates excellent practices, summarizes insufficient experiences, and improves the digitalized control system for UHV tests.

By analyzing the quality of test data, test operation details and risk identification in the platform, comprehensive evaluations of the work quality and effectiveness of test personnel are carried out to form personalized analysis reports, urging targeted rectification and improvement of work of teams and personnel.

Through post-operation team meetings, the problems exposed by personnel, equipment and collaborative operations during the test process are promptly summarized and reported by the test leaders to the digital control platform for subsequent unified coordination and rectification.

State Grid Anhui Electric Power's power science research institute, in line with the intrinsic requirements of equipment management digital transformation, has constructed a fully digitalized control system for the entire process of UHV large-scale tests, addressing the difficulties faced in test work such as involving multiple participating units, difficult coordination and control, long operational processes and high safety risks.

This effort has enhanced the standardization of test operation processes, the intelligence of equipment, the transparency of operations and the lean management level of control, promoting the actual and in-depth implementation of safety production and supporting the company's equipment management digital transformation.
