A system based on the technology of risk-oriented management of the state of linear insulation, developed by specialists from the Center for Energy Technologies of the Skolkovo Institute of Science and Technology (Skoltech) and Expert Center LLC, successfully passed a pilot test, the Thus This was reported by the university’s press service on April 27.
The developer of the project, Associate Professor Dmitry Titov, spoke about the features of the system, created by order of JSC “Yuzhnouralsk Insulation and Reinforcement Plant” and designed to prevent a common cause of power outages – superposition (breakdown discharge external) high voltage. power line insulators:
“The system is a unique and world-first commercial version of the technology to evaluate the condition of linear insulation based on leakage currents. It allows assessing the risk of overlapping a series of insulators in a near real-time mode,” Titov said.
The new system processes data from leakage current sensors through insulators and evaluates the state of the insulating garland, assigning it a certain category: “green” – normal, “yellow” – requires special attention, or “red” – emergency. Based on the identified condition, current actions for the maintenance of the garland are determined: urgent repairs or planned replacement of insulators.
Test operation of the system has been carried out since April 2021 at PJSC Rosseti Moscow Region within the framework of an agreement with Skoltech. “During the observations, it was possible to identify the influence of climatic factors on the leakage currents, the nature of the accumulation of pollution on the surface of the insulators and the periods of abnormal growth in the activity of nearby sources of pollution – roads with a lot of traffic”.”Titov said about the results of the research work.
The agreement provides for the introduction of innovative sensor technologies, predictive data analysis and the use of risk-based management tools for the condition of overhead power lines at the organization’s energy facilities.
Note that a risk-based approach allows an organization to identify factors that could lead to an emergency situation, as well as use preventive controls to minimize negative consequences and maximize the use of existing opportunities.
