2. Supervisory Control and Data Acquisition (SCADA) Development


   The Integrated Power Technology Corporation™ hereby evaluates developing a Supervisory Control and Data Acquisition (SCADA) suite of client and server side applications and suggests the platforms on which they run. Finally we evaluate candidate PLC Manufacturers for their platforms on which to develop this application, as well as open source software in comparison to proprietary software functionality.

   Development of the Supervisory Control and Data Acquisition (SCADA) system requires several diverse on-line integrated server-side applications, and client side user interfaces to access them. Remote control system development, Supervisory Control and Data Acquisition (SCADA) database development integrates:

  1. Weather prediction and tracking data aggregation - Geospatial Information System (GIS) development data from a number of satellites and map servers on one server, opensource Geoserver, client-side Geographic Resource Assessment System Software, GRASS GIS etc.
  2. Commodity price and currency exchange rate database development for Levelized Cost of Energy (LCOE) Assessment;
  3. System Configuration Module Database development comprising patented mobile structures and other hardware specifications, datasheets, bill-of-material (BOM) costs, material safety data sheets (MSDS); This database may also contain Customer Relation Management (CRM) and Supply Chain Management data.
  4. Unmanned Marine Vehicle (UMV) control with the ultimate goal of high-level autonomy. The UMV control development will require an emulation platform of a Programmable Logic Controller (PLC) to simulate the vessel navigation, propulsion, and operation local control systems.
  5. Vessel Velocity Performance Prediction (VPP): from a knowledge base of those who have designed sailboats and propelled vessels, adapt VPP's to enable the user to predict energy recovery by vessels specified in the configuration database (3). ANSYS and/or Solidworks Premium and Solidworks Flow for Computational Fluid Dynamics (CFD) dynamic simulations, Solidworks and especially ANSYS Fluid Dynamics both being de facto standards in mechanical design and CFD; Hire a full time structural or mechanical engineer to design, model and simulate candidate configurations.
  6. Path cost or path yield analysis algorithm development. For instance U.S. National Renewable Energy Lab's (NREL's) "Homer" adapted especially for automated analysis of hybrid mobile ocean energy systems while also providing the mapping capabilities of ECDIS. The top-level integration of this data in parts (1) through (5) endows operators with the mathematical rigor to make prudent decisions on configuration, M&O, and navigation.

Detailed Discussion

   The SCADA development goals consist of establishing a computer server comprising mobile structure component configuration data, install a functional stack based on open source standards such as OSGEO, Geoserver or Mapserver, PostgreSQL, etc. then determine interoperability issues with client software such as Geographic Resource Analysis System Software (GRASS), then determine costs or interoperability issues with obtaining data from any or all of the aforementioned satellite systems.

   Aside from providing a database containing static elements from which to make the configuration determinations listed above, critical functionality to work towards would include a GIS comprising not only Geospatial but also dynamic temporal data including wind speeds, insolation data, sea conditions, and weather tracking and prediction to avail data from which to base M&O and navigation decisions. Once an operator determines the best configuration for the mobile structure, its corresponding VPP/CFD model may reside on the SCADA server with which a path-dependent cost or yield analysis module applies the dynamic data to the VPP/CFD model to ultimately inform M&O and navigation decisions.

   The software design specification will delineate which control algorithm functions locally on the vessel or within both the local vessel control loop on the vessel's PLC and the SCADA/GIS/GPS remote control system server. Such delineation exemplifies the early milestone goal of control system configuration and functionality analysis, and forms the essence of much UMV research including: Multi System Mission Control for Teams of Unmanned Marine Vehicles – Software Structure for Online Replanning of Mission Plans and Nested Autonomy for Unmanned Marine Vehicles with MOOS-IvP. Creation of the specification of integration of the VPP analysis software with the GIS component into the SCADA system to enable analysis of optimal route through weather systems will also demarcate an early milestone.

   The design specification will document the preliminary draft top-level control algorithm for both the local control loop and the SCADA/GIS/GPS remote control system. Choices of high bandwidth control input accessory sensors such as motion video depend upon physical layer of choice, i.e. SCADA point-to-point UHF, Iridium (telecommunication satellite), or else CDMA. Early milestones will consist of SCADA configuration, cost and functionality analysis, and top-level control functional description. As top-level software integration typically tends to occur towards the end of the development of the design cycle, a high-level PLC emulation system will function upon completion of prototype design stages, with completing final software integration comprising a considerable portion of the prototype development.

   An integrated geospatial information system (GIS) database and satellite global positioning systems (GPS) data feeds enable controlling the navigation of the vessel. The GPS control systems will include integrated real-time streaming weather data so as to provide the optimal geodetic navigation path into a maximal wind or insolation system to gain the largest capacity for return.

Proposed Approach

   Integrated Power Technology Corporation™ proposes to define an integrated GIS-GPS system that is used to control the vessel using a satellite technology based TCP-IP network solution. This solution would involve developing a supervisory control and data acquisition (SCADA) system that interfaces with a geospatial database containing both navigational mapping data and real-time weather data. The project would also involve the development of algorithms that integrate the on-board vessel sensor data with the weather and GIS data. The system would be controlled using a human machine interface (HMI) solution developed as a user-friendly graphic user interface (GUI). The HMI GUI would be developed as both a desktop and web based application to enable a variety of control options for systems controls, operation and maintenance functions.

   The SCADA/HMI systems would be integrated with the vessel through a series of clustered servers hosting the server side functions communicating with the client side GPS control application running on the vessels. The on-board application would be fed the parameters delivered from the aerodynamic/hydrodynamic performance simulation software models, the onboard sensor data and integrate the real-time weather and environmental data and determine an optimal routing through weather systems. Additionally, a server-side optimization algorithm will be developed to access configuration variable assessment and present choices to the HMI to maximize the SCADA system performance.

   The system would be developed using client server technologies with servers hosting and controlling the GIS – GPS databases, running computational algorithms on client provided data feeds. The HMI would be developed as a server-side application with secure remote client control application connection.

   The SCADA system includes input/output signal hardware, controllers, HMI (Human Machine Interface), networks, communication, and software.

   The VPP CAD component model would be integrated into the HMI to allow for realtime visualization in a 3D virtual reality simulation. This tool would be used to fine tune, test and calibrate the SCADA navigation systems.

   This development effort would be accomplished, wherever feasible, using open source standards (Geoserver, client-side Geographic Resource Assessment System Software, GRASS GIS etc.) and software to minimize the software licensing fees and constraints.

Early SCADA Development Deliverables

   Early project deliverables from the SCADA Development team will include a mid-level systems design guide report consisting of an executive summary, detailed report, supporting drawings, tables and figures.

   The design guide would include a number of sections detailing the architectural tiers of the system, process controls, HMI Visualization interfaces, data analysis and supervisory servers, data storage, network communications layers, all hardware, SCADA object tags definition, software development definitions and overall systems integration plans.

   By completing the SCADA initial design process, the project will enable validation of the feasibility of one or more configurations of the proposed energy extraction and delivery vehicle. In all configurations, remote control based on GIS/GPS/SCADA remains at the highest level of integration into the complete system. The design work completed in the prototype design stage will guide applicability through prototype development and later full production in evaluating candidate configurations of mobile hybrid structures specific to each geographic location proposed.
