en.Wedoany.com Reported - Recently, the first fully autonomous and controllable demonstration renovation project in the Yalong River Basin, led by NARI Technology Co., Ltd., the Guandi Hydropower Station's 600 MW unit main and auxiliary integrated fully autonomous and controllable retrofitting project, was successfully connected to the grid for power generation. This project precisely aligns with the national energy security new strategy, successfully completing the domestic iterative upgrade of the station's computer monitoring system, addressing the shortcomings in the autonomous controllability of core equipment, and ensuring the stable transmission of clean hydropower from the basin through solid technological upgrades, providing a practical and implementable exemplary case for the construction of a new power system.
As a key green energy channel for the national "West-to-East Power Transmission" strategy, the Jin-Su ±800 kV UHV DC project undertakes the crucial function of cross-regional transmission of clean hydropower from the Yalong River. It is a critical transmission corridor for optimizing national energy resource allocation, ensuring electricity supply for eastern load centers, and promoting the achievement of the "dual carbon" goals. This retrofitting focused on the core control links of the sending-end units, specifically optimizing unit regulation performance, effectively enhancing the station's response speed, regulation accuracy, operational stability, and security protection level, thereby solidifying the front-end technical defense for the safe operation of the UHV transmission channel. After the project's commissioning, it effectively eliminated the risk of dependence on foreign core equipment, comprehensively enhanced the autonomous operation, maintenance, and controllability capabilities of the sending-end station, ensured the stable supply of cross-regional green electricity, and provided a standardized template for the large-scale domestic upgrade of basin hydropower.
Leveraging years of accumulated scientific and technological expertise in hydropower engineering, NARI's subsidiary, NARI Hydropower Company, collaborated with Yalong River Hydropower Development Co., Ltd. to tackle key challenges, integrate core technologies and industrial resources, and successfully achieve the domestic replacement of the station's complete core control system. The entire station is equipped with NARI's N510 series autonomous and controllable PLCs and a full set of self-developed core software and hardware, replacing traditional imported control equipment, eliminating operational safety risks of the core system, and establishing an autonomous, controllable, intelligent, and efficient smart control system for the station.
