俄研发出提升电网可靠性的新设备

Core Insights - Researchers at Tomsk Polytechnic University have developed a new three-phase inverter that could potentially double the reliability of power grids [1] - The inverter features a modern control system that allows renewable energy sources to participate in grid regulation, simulating the operation of traditional synchronous motors for wide-range voltage adjustment [1] Group 1: Technology and Functionality - The basic inverter can adjust voltage amplitude and frequency, thereby regulating power and transmission angle, which determines the extent and duration of operational parameter fluctuations after disturbances [1] - The new control device can link various parameters together, enabling appropriate responses to external disturbances, thus preventing greater losses from arbitrary parameter changes [1] - The new inverter significantly simplifies the connection and operation of renewable energy generation equipment and facilitates the integration of hybrid battery systems into the grid [1] Group 2: Impact and Applications - Preliminary estimates indicate that the device can reduce the amplitude of operational parameter fluctuations during disturbances by nearly half [1] - Prototypes based on this research have been constructed, and design documents for test samples are currently being prepared [1] - The research aims to ensure reliable and seamless integration of different generation and consumption facilities, laying the groundwork for next-generation high-voltage transmission lines, including high-voltage direct current (HVDC) systems and flexible alternating current transmission systems (FACTS) [1] Group 3: Regional Significance - Experts believe that the application of these devices in isolated power systems in regions such as the Far East or the Arctic will be particularly effective due to lower generation and consumption levels [2] - The combination of relatively small storage systems with the newly developed converters is expected to have a greater impact on power quality in these areas [2]
