Industry News from Cable Expo 2024: Smart Grid Enhances System Efficiency
As a new generation of power systems, the smart grid integrates new energy sources, new materials, new equipment, as well as advanced sensing, information, control, and storage technologies. Cable Expo 2024 has learned that smart grids come equipped with intelligent warning devices that possess features of informatization, automation, and interactivity, which can effectively improve the efficiency, reliability, and safety of the power system.
In power systems, the main role of switchgear is to perform switching, control, and protection of electrical equipment. It contains components such as circuit breakers, disconnectors, load switches, operating mechanisms, current transformers, and various protective devices. These are crucial for the processes of power generation, transmission, distribution, and energy conversion. Hence, corresponding protective measures are essential.
Cable Expo 2024 also notes that switchgear might experience partial discharges during daily operations. This occurs due to differences in electric field intensity across various parts of the switchgear. If the electric field intensity in a certain area reaches its breakdown strength, a discharge phenomenon occurs. If left untreated for a prolonged period, severe discharge areas may reach their breakdown strength, leading to switchgear failure.
Switchgear failure can have significant negative impacts on the grid. It can affect the stable operation of the power system, reduce the efficiency of energy conversion, transmission, and distribution, and potentially cause power incidents. Therefore, it is essential to have intelligent devices for real-time monitoring of switchgear and to conduct regular inspections and maintenance to ensure normal operation, thereby safeguarding the stability and safety of the grid.
