Auto Sequencing Control System
Nelumbo has developed & delivered multiple Auto Sequencing Systems (ASS). These are intelligent control systems designed to automate and optimize the sequence of operations in various industrial processes and power plants. By automating repetitive
tasks and ensuring that operations occur in the correct order, ASS can significantly improve efficiency, productivity, and quality.
They offer features like sequence programming, real-time monitoring, automatic adjustments, data logging
, and integration with other systems. ASS are used in power plants, manufacturing, process industries, utilities, and water treatment plants for better outputs
Digital Governing Control System
Nelumbo has developed microprocessor based Digital Governing Controller for Hydro Turbines. Controller has clocked 5 years+ of successful performance.
Digital governing controllers are crucial for regulating turbine performance. They use advanced algorithms to monitor and adjust turbine speed, load, and other parameters. By precisely controlling these factors, digital governors ensure efficient operation and enhance overall system stability.
Brushless Excitation Control System
Nelumbo provides wide range of Brushless Excitation Control Systems using latest microprocessor based AVR modules of different makes i.e. ABB, Basler, Nidec & Deif.
Both redundant & non-redundant configurations shall be supplied as per system/project requirements.
Unit Control Boards / PLC based Control Panels
Nelumbo manufacture PLC based Unit Control Boards (UCBs) for Turbines, Engine Control System, MIV Control Panels, Dam Gate Control Panels, Common Control Panels etc for Manual as well as Auto operation of TG/DG sets
Nelumbo has delivered UCBs for 100+ machines in last one decade with stand alone as well as Redundant processor based control systems in India and abroad.
Synchronizing Control System
Synchronizing is one of the key control system for connecting two Synchronous Generators or a Synchronous Generator with Grid. Nelumbo provide both Manual, Semi Auto & Automatic Sychronizing Control Systems for all type of power plants using Deif make controllers.
Nelumbo has delivered synchronization systems upto 500MW rated Synchronous Generators.
