The equipment delivered to the Hida Converter Station is the first HVDC equipment in Japan to establish an aerial interconnection between grids with different frequencies. The company has the world's best *3 HVDC technologies, reflecting their engagement in approximately 120 systems, or almost half of the world's DC power transmission systems with a total wattage of 130,000 MW. *2 Hitachi ABB Power Grids established in July 2020 was the first to commercialized HVDC in 1954. In most projects related to the installation HVDC *1 in Japan, Hitachi has been in charge of technological development and project arrangements and contributed to the maintenance of Japan's high quality power system that is best in the world in availability. Therefore, with an eye toward expanding renewable energy, the materiality of HVDC is increasing from the perspective of transmitting power from large offshore wind power generation facilities in remote areas to the places where the power is used, and the perspective of increasing the capacity of the interconnections of regional systems. It also reduces the loss of power when transmitting power over long distances and offers other features that are beneficial for the expansion of the systems. HVDC enables the interconnection of systems using different frequencies. The installation of the converters, which began in August 2018, has been completed. The equipment uses the line commutate converter High-Voltage Direct Current (HVDC) power transmission technology to achieve the interconnection of systems with different frequencies through the conversion of alternating current into direct current. In this project, Hitachi received an order for a frequency converter to be installed at Chubu Electric Power's Hida Converter Station that included installation and testing. In the wake of the Great East Japan Earthquake that occurred on March 11, 2011, the new facility was purpose-built to increase the interconnection capacity between the different areas and enhance the power supply capacity in the event of a large disaster. ![]() The Hida-Shinano frequency conversion facility is a direct current transmission system with an interconnection capacity of 900MW, connecting the 60 Hz-based Chubu Electric Power area and the 50 Hz-based TEPCO area via an approximately 89 km long aerial cable. ![]() ("Chubu Electric Power"), to which Hitachi delivered a line commutate converter high-voltage direct current ("HVDC") system. ![]() ("TEPCO") to be connected to the Hida Converter Station of Chubu Electric Power Grid Co., Inc. (TSE: 6501, "Hitachi") today announced that the operations of the Hida-Shinano frequency conversion facility have commenced, enabling the Shin-Shinano Substation of TEPCO Power Grid, Inc. Completion of Chubu Electric Power Grid Hida Converter Station Equipped with Hitachi's Frequency ConvertersĬontributing to a stable supply of electricity by enabling efficient interconnection between Tokyo and Chubu regions with HVDC Technology
