Complete overview at any time The development of Bachmann‘s open, flexible and future-oriented Wind Power SCADA (WPS) system was based on its many years of experience and knowledge acquired in the wind power sector. Using pure web technology as a basis, a wide range of different terminal devices can be used for running the SCADA system – a browser is all that‘s needed to access extensive and detailed information on the entire fleet.

Faster engineering to the target The WPS sector-specific system solution is a perfect addition to Bachmann‘s WindTurbineTemplate (WTT), a turbine controller software, which provides the most important components, analyses and functions for the operational control of a wind turbine. WTT is based on the data structures of the IEC 61400-25 standard and depic ts all process values using the standard compliant data area. This enables standard compliant components created in WPS to be instantiated as objects from the prepared libraries. The process data connection is therefore already completed and the turbine can be visualized with its components by simply using drag and drop to add the instance. This considerable reduction in development effort through the use of library components helps you to achieve your goal faster and more economically.

Field-proven technology for all areas WPS is based on the generic atvise SCADA product from Certec, a company belonging to the Bachmann Group. Thanks to its multiclient server architecture, atvise SCADA provides the ideal basis for WPS. Multi-lingual functionality as well as device and operating system independence complete the portfolio for keeping wind power in view from anywhere in the world. PCs, tablets or smartphones can access a WPS ser ver simultaneously. The required information is scaled automatically and shown correctly on the target device.

Safe operation – made easy Bachmann WPS covers a wide range of operating levels – from the control center to the

farm management system, right through to the individual turbine. Secure access to the turbine is ensured by means of locationdependent priorities and configurable, userspecific access permissions. A thorough logging of all activities at the turbine, as well as commands and parameter changes made via the WPS system, enable full tracking for maintenance in the event of a fault. An extensive reporting system completes the traceability required for plant operations.

Standard communication via the OPC UA connection to external devices and controller systems Using OPC UA as the communication protocol allows external devices or subsystems, such as weather or grid stations, to connect directly to the WPS system, provided the devices also support the IEC 16400-25 compliant structures. If this is not the case, a gateway allows several other protocols such as the energy protocols for example DNP3 in accordance with IEC 60870-103/-104, IEC 61850 or fieldbus protocols, such as Profinet, Profibus, CANBus etc., to be connected and the relevant data to be shown in WPS.

The visualization is adjusted automatically to the display device to ensure ergonomic operation even on mobile devices such as tablet PCs or cell phones.

WHY CONDITION MONITORING? Focus on efficiency and cost saving

In continuously striving to drive down costs, it is imperative that you can understand what is going on in your machine. By tracking the health of your machine you protect not only your investment, but also optimize your maintenance practices, so that you intervene before consequential damage, but avoid unnecessary measures.

Example of repair costs*

Case report One of the gearbox types we monitor is susceptible to a major failure mode. Our monitoring team worked with the customer to identify a frequency band which would reliably inform us of changing conditions on these types of gearboxes. Based on this parameter, an alert was sent to the customer in late August. The customer inspec ted, but could see no obvious problems, and attributed the change to standstill marks; however we were not convinced. The trend continued, and fur ther alarm levels were exceeded. On our advice, and with support from the manufacturer, the customer made the decision to prioritize the exchange of this gearbox.

Benefits Our service monitors the health of your wind turbine allowing you to concentrate on optimizing your procedures. This leads to:

Increased Availability

Early detection of faults allows timely intervention before failure occurs Accurate diagnoses based on our extensive experience and knowledge bank

Risk Management

On exchange it was found that the ring gear had indeed begun to suffer from the damage mechanism, which starts beneath the tooth surface. So it is not always apparent via endoscopy and sometimes even until it is too late.

Our experience delivers in-depth knowledge of your wind turbines, which allows you to: Understand the status of your wind park Confidently challenge the manufacturer or service provider from an informed position Improve risk analysis when considering how long to run with minor faults

Before we found this particular indicator, gearboxes were known to fail catastrophically, destroying the tooth surfaces and bearings. In this case only the pictured gear had suffered any damage, thus saving significant refurbishment costs.

Cost Reduction

Condition based maintenance and maintenance optimization leads to reductions in maintenance cost


SCADA RETROFIT CASE STUDY Retrofit of SCADA for 155 GE 1.5 sle turbines


A large US wind farm owner/operator was concerned with the OEM supplied solution and its restrictive nature. They wanted to upgrade the SCADA so security vulnerabilities were patched, and not have features and data access further restricted. Comprehensive data and flexibility for their data analytics program was a primary focus as was using maximum performance data and gaining increased security. With a self-performance model for operation, the flexibility and ease of adapting additional features and analysis within the Bachmann Wind Power SCADA (WPS) solution were also key drivers to go with Bachmann.

Overview With a need to upgrade CPU controllers from the discontinued MP2xx/MPC2xx controller line to Bachmann’s latest MC2xx controller, coupled with the constant threat of cyberattacks tighter security needs, a large owner/ operator in West Texas awarded Bachmann a large SCADA retrofit project for their 155 GE 1.5 sle turbines. Prior to selection as SCADA partner for the site, Bachmann first deployed a 3 turbine, 6 month trial for the site to evaluate the WPS platform risk-free. Customer requirements were fully detailed ahead of deployment which consisted of enhanced security to protect the site against cyber attacks, complete access to turbine data, removal of VisuPro PCs with web based access, site specific curtailment commands, and database sharing access.

Cyber Security The Bachmann M1 system has a multilayer security architecture ranging from 0-5, with 5 being the highest level of security (SSL/TSL) and fulfill the NERC cyber security requirements. With the previous security level set to 0 (no security), site access was granted freely to both operators and hackers alike. Through WPS’ token-based write access, multiple users were able to simultaneously access WPS with write access automatically assigned based on login credentials or proximity to the turbine, while accounting for safety. With user logins and parameter changes saved and archived, operators have full transparency allowing work to be tracked at any time.

Data Access Data access is provided through variables mapped according to the IEC 61400-25, the international standard defining communication for monitoring and control of wind power plants. This ensured that the site was provided open access to their turbine data with standard nomenclature defined for turbine param-

eters. Standardizing turbine data allowed for interpretation of signals regardless of turbine make, allowing the customer to move towards a single SCADA platform for their mixed fleet. The level of data access provided by WPS, along with the flexibility and customization options, allowed the site to free themselves from their OEM dependence. They now could implement additional features (such as site-specific curtailment commands) within WPS using their own internal resources or assistance by Bachmann. WPS’ database sharing allowed for 10 min SCADA data to be exported to the site’s data historian via OPC-DA.

Removing VisuPro PCs During the trial period, WPS operated in parallel to the existing GE SCADA system and the VisuPro PCs. This allowed the customer to evaluate WPS with minimal impact on their operation. Upon successful completion of the trial, the customer chose to remove all VisuPro PCs and rely on Bachmann’s web-based WPS solution for all SCADA operation. Maintenance level access was granted by connecting a laptop directly to the M1 controller located downtower and opening the web-based WebMI turbine visualization on a simple web browser without needing to download any plugins.

Conclusion Upon completion of the WPS retrofit, Bachmann was able to provide a flexible, cost competitive, cyber secure alternative to the OEM, based on IEC standards. The site’s security vulnerabilities were patched, the turbine PCs removed, complete access was granted, and the site was trained to continue developing additional features themselves within Bachmann WPS. With WPS, the site was able to achieve the independence they needed with their next SCADA platform, while ensuring a low cost of ownership would be realized throughout the lifetime of their park.
