Abstract

CLASSIC USE OF SCADA AND HOW TO IMPROVE FOR A BETTER MAINTENANCE

Introduction

Nowadays all commercial wind farms are equipped with a Supervisory Control and Data Acquisition (SCADA) system. Therefore it is necessary to take the maintenance issues to an upper level to be sure the best information quality is available to improve maintenance. WinCC OA is the integrated SCADA solution for the most effective management of wind turbines and (multiple) wind farms.

Approach

The engineering of SIMATIC WinCC OA optimized for non-homogenous networks reduces your costs and time enormously.
Scalable, networked control system servers grow as the task grows.
Integrated regional control desks, used in distributed systems, support local service groups and increase disaster tolerance.
If personnel are distributed over an extremely large geographical area or if a large number of wind farms have to be managed, the scalability of SIMATIC WinCC OA across several spatially distributed servers is a distinct advantage.
In this case each server is a stand-alone control system responsible for one area or region.
If these are networked - for example, in a star configuration - hundreds of these autonomous local control desks can be connected using just a few central control desks.
Which in turn - without any connection to the process and without the need for additional configuration work - have full access to all measured data, alarms, histories and configurations of the wind turbines.
Any star or line topologies could be used for this purpose. SIMATIC WinCC OA has already made this technology of the distributed system the preferred system in numerous international reference projects.

The classic use of SCADA in the wind farm service:

Requirements of service and operations management
1.) Requirements for managing operation
a. High availability and productivity of the plants
• Reliable data
b. Simple operation
• Fast access to all plants
• Uniform intuitive operation
• Uniform data structures
• Only one login
c. Integrated maintenance management
• Organization of personnel
• spare parts
• tools
• documentation and resources

2.) Requirements of service personnel
a. Highly convenient diagnostic
• Full transparency due to access to all available data for the service – at
all levels
• Full access to historical data of all machine data – on demand, with low
operating costs
• Simple, fast access to current master data
• When necessary also access with a mobile device


Main body of abstract

Distributed systems

WinCC Open Architecture offers the option of “distributed systems” for large and/or geographically distributed applications.
Distributed systems enable any number of stand-alone systems - 2 to 2048 - to be linked
via a network.
Each subsystem can be configured either as a single-user or multiusersystem - redundant or not - in each case.
In this context, a subsystem means a server on which an Event Manager is running.
Each system can process and display data from the other systems.
The use of distributed systems (“Distributed Database”) ensures access to online values, alarms and histories for each system.

SIMATIC WinCC Open Architecture – Wind power plant service portal
Siemens has launched a new two-part solution to address the needs of wind turbine manufacturers as well as independent service providers: a turbine SCADA with long-term database and a central service portal. Both systems come with a standardized operating concept and integrated communication. Use of SIMATIC WinCC Open Architecture provides a foundation to open up scope for customers to upgrade the service portal for their own needs. Qualified Siemens solution partners are available worldwide if help is needed to make adjustments and implement upgrades.
The integrated architecture and communication facility and the use of long-term databases on the turbine or farm level mean that service engineers can use a central application in the control desk to access the complete range of up-to-the-minute data from all connected turbines to carry out any kind of comparative analysis. This eliminates the need to dial into each turbine separately and change between different applications, while still allowing service teams unrestricted access to any online data, alarms and histories without compromising optimum troubleshooting and analysis. A smart data management system allows unrestricted data access to even low bandwidth connections.
The open nature of SIMATIC WinCC Open Architecture along with its long-term compatibility provides the optimum customer investment security over the long term. There are currently a large number of running applications based on SIMATIC WinCC Open Architecture that can still be upgraded and maintained even after al-most 15 years.

Conclusion

To guarantee improved maintenance capabilities and state-of-the-art monitoring and control
a SCADA system should combine follow features:

• Integrated web-capable SCADA solution for the management of wind turbines, wind farms and central multi-farm service portals based on the SCADA system SIMATIC WinCC Open Architecture. Its open concept and the wide variety of available interfaces allow free configuration and optimum scope for upgrading.
• Open SCADA architecture with integrated communication
• Central service portal for turbines
• Ranging from machine- level HMI in the turbine up to a state-of-the-art SCADA for single/multiple wind farms
• Providing an on demand access to any real-time and historical data, video-streams, etc.
• Configuration of wind farms and turbines without any additional configuration
• Should be able to be adapted very flexibly to customer specific requirements
• High investment security for customers due to the long-term maintenance

With WinCC Open Architecture you can quickly adapt the control and visualization of wind turbines or wind farms to suit current market requirements and be one step ahead of the competition. This solution enables you, to implement easily new processes/ideas/visions, without having to negotiate any technical barriers. Existing systems are unaffected.
WinCC Open Architecture can be integrated into the established workflow.
You are spared any larger cut-overs across the company as a whole.
All developments can be programmed in-house, so you gain independence and your creation is automatically protected.
OEMs also benefit from the opportunity to construct and introduce standardized solutions for their specific applications.

Thanks to its unique system properties, SIMATIC WinCC Open Architecture fulfills the most stringent requirements, especially also in infrastructural applications like wind energy business.
