In recent years, the development of renewable energy sources such as wind power and solar power has put more pressure on the stability of the power system because these energy sources change from time to time and are greatly influenced by weather conditions. weather. To overcome the above situation, as well as meet the actual needs, factories are required to comply with the directive on frequency regulation issued by the state. Therefore, choosing the hydro turbine speed control solution – Nexus Controls provided by S5T is the solution that meets the law, while helping to increase efficiency, save costs, and optimize operation for users.
With hydroelectric turbines, speed regulation is essentially regulating the flow of water into the turbine by changing the blade opening. The important task is to sense even the smallest change, to ensure the necessary balance in the system. Currently, Nexus Controls is known as the leading prestigious brand in the world, providing speed control equipment for hydroelectric plants. Through the process of actual installation and deployment, the product has shown its effectiveness in optimizing performance, saving costs, and at the same time convenient for warranty, repair and upgrade:
Operating Nexus Controls hydro turbine speed control solution
Software Optimum C:
+ It is a software that integrates programming tools for controllers, building operating interfaces, and storing historical data.
+ The software is developed by the manufacturer of Nexus Controls itself.
+ OptimumC software is used to connect the speed controller to ensure repair, testing, calibration, and troubleshooting (software that connects the computer to the PLC for testing and calibration; software to capture waves and standardize errors. ).
+ Optimum C software is open design so that the user can change the operating parameters when necessary.

The Nexus Controls provided by S5T can be used in all units of the hydro power plant.
S5T engineer and customer in the project of installing Nexus Oncore hydroelectric speed control system
In order to meet the requirements of power system stability, the Ministry of Industry and Trade issued Circulars No. 25/2016/TT-BCT and Circular 30/2019/TT-BCT on requiring units with a capacity of ≥30MW to perform Primary, secondary and PSS frequency modulated. Facing the new requirements of the power system for units with a capacity of >30MW, the plants have two solutions to solve the above problem: Adjust, test on the existing speed control system or replace the system. old speed regulation by a new modern system, meeting the requirements promulgated by the state.
For calibration and replacement, the job is often difficult because the hardware equipment is often too old, the software is too outdated, and it is not suitable to calibrate to meet the frequency regulation requirements. The reality also shows that there are very few successful units with this option. Therefore, the Nexus Oncore accelerator system provided by the S5T is the solution to the above problem. We are an agent of Nexus Controls since 2019, have upgraded many units of Song Pha Hydropower Plants, An Khe Hydropower Plants, Buon Tua Srah Hydropower Plants…
S5T owns a team of experienced experts with in-depth knowledge, who have participated in many practical projects such as:
