Hardware Test

Overview

The Bladed Hardware Test module (BHTM) allows control system hardware to be connected directly to Bladed simulations. Its key features enable the user to:

• Test PLCs, HMIs, SCADA systems, pitch system interfaces, power converter interfaces and combinations of these systems working together.
• Verify hardware operation in the factory and reduce time on site.
• Develop interactive and batch procedures directly within the Hardware Test user interface.
• Use and recycle procedures for repeat tests and automatically generate Microsoft Word test reports.

Real-time simulation

The module includes a real-time simulation engine so that, on a fast PC, full Bladed dynamic simulations can be operated in real time. Models include full turbulent wind field, blade element aerodynamics, modal representations for blade, and tower dynamics and almost all the other simulation capabilities of Bladed. Real-time plots and run time user interaction with tests for triggering events are also included.

Add Microsoft .NET code scripts directly to the Hardware Test module to extend the simulation capability into new areas and emulate custom transducers, simple thermal dynamics, hydraulic power pack sequences etc.

Connectivity

The user interface provides an intuitive and powerful means of mapping hardware and simulation signals. Hardware inputs and outputs are freely assignable to and from simulation inputs, outputs or user written script expressions. Signal calibrations and mappings are all implemented with .NET code fragments typed directly into the Bladed GUI.

Standard interfaces are provided for direct analogue and digital signals (via PCI IO cards), Ethernet TCP and UDP packet data, the OPC standard and a variety of controller proprietary standards. Interfaces to alternative hardware can be written as .NET plugin code and integrated with the Hardware Test module; DNV can provide these plugins at cost or train the user to create their own.
