Moxa's Solution for Offshore Wind Power

Offshore wind power applications are similar to typical onshore wind turbine projects. Both types require careful planning during the construction phase, and it is best to manage wind turbine systems remotely from a central control center. In order to keep the installation cost at a reasonable level, most wind turbine sites are made up of many turbines. In fact, the turbines are often erected in rows, in the same way that crops are planted.

System Requirements

Location
Typically, most offshore wind turbine projects are located along coastlines where the wind speed is greater than onshore. However, offshore environments are often subject to critical conditions, such as corrosion and extreme temperatures, making safety certification and long MTBF a must. Since wind power plants require a huge investment of time and money, designers must select high quality products with specialized features.

Transmission Distance
Electric transmission lines and network control lines are buried under the seabed. In some cases, the first wind turbine site is located more than 3 km from the control center. An inefficient network design can dramatically increase the cost of cabling. For this reason, determining a good location for each wind turbine, and implementing a reliable network with nonstop network communication can have a big impact on future maintenance costs.

Maintenance
The cost of sending engineers to a wind turbine site to collect power meter data or to conduct regular maintenance can be very high. This is particularly true since ships or helicopters must be used for transportation. Traditionally, maintenance technicians had to be winched down to the wind turbine platform from a helicopter if the sea was too rough to approach the structure by boat. Not only is it expensive to rent a helicopter or boat, but it is also extremely dangerous to send engineers into such a hazardous area. Moreover, if the weather conditions are particularly fierce, then work on the wind turbine may need to be postponed for an unknown amount of time. Being able to set up a reliable control network with a SCADA system can greatly simplify the task of managing and controlling a wind turbine farm.

Control Network
Ethernet is the perfect solution for reducing the total cost of setting up and maintaining a communication network. By using Ethernet, engineers do not need to learn proprietary protocols, which are only supported by specific vendors at a high price. Engineers can also concentrate on determining which product functions and features are needed.

    PRODUCT APPLICATIONS

    Making Traditional Factories more Advanced and Automated

    Overview
    Upgrading from a traditional factory to a modern factory requires more than just replacing machines and equipment. More importantly, modern factories require an upgraded communication and control system. Upgrading the communication system can save much time and cost by reducing engineers' travel time. This includes the time spent moving from station to station inside the factory, as well the time needed to travel between home and factory to handle emergencies. Overall, upgrading a factory's control system provides engineers with greater flexibility.

    Benefits from Moxa
    Moxa provides a wide range of products that can be used to create a modern factory.

    • Serial Communication Boards
      Expand the number of serial ports for a PC to connect serial machines directly to the PC, or to connect modems for remote control.
    • Serial Device Servers
      Connect one or more serial machines (PLC, CNC, etc.) to the Ethernet network to provide remote management and control from any PC on the network.
    • Wireless Device Servers & Access Points
      Some factories can take advantage of the wireless solution to avoid the hassle and expense of wiring machines to each other and to the network.
    • Media Converters
      Convert between RS-232 signals and the ever popular RS-485 signals, or create a reliable extension that can be used in high-noise environments.
    • ready-to-run Embedded Computers
      All-in-one embedded computers can be used for specialized computational tasks; you will no longer need to send all data back to a central backend computer.
    • Industrial Video Servers
      Maintain entrance security by connecting legacy cameras to an Ethernet network and storing important video images in digital format.
    • Ethernet I/O Servers
      Create a real-time monitoring and control system; e.g., you can easily check the output of temperature sensors to maintain the safety of your factory system.

    Monitoring/Management System for Petrochemical Plants

    Sinopec Oil Ltd. has facilities in Jeng Hai that are based on the Shanghai Long River estuary. The big petrochemical plants controlled by the company include Sinopec Shanghai Oil Ltd., Sinopec Yangtz Oil Ltd., and Sinopec Yijeng Oil Ltd. In fact, Jeng Hai became the first oil reserve base that came under the purview of the National Development and Reform Commission. China Automatic Control Technology Ltd. with its many years of experience in the petrochemical automatic control field has bid successfully for many automatic monitoring control projects in the Jeng Hai oil reserve base case.

    There are six oil tanks that need to be monitored in this oil reserve base. Once the monitoring parameters are transferred from each tank to a PLC, the PLC will take care of the logic control immediately. The host computer uses assembly software to collect PLC data to do on-site monitoring, warning, and data management. The host computer uses EDS-405-MM and ED6008-MM to form double rings for network redundancy; there are two EDS-405-MM switches in the oil tank area and four ED6008-MM switches in the central control room. Network redundancy ensures that the network connection will not fail due to a break in the fiber, or switch failure. Also, relays can notify engineers to repair the fiber or switches when they fail.

    EtherDevice™ Switch ED6008 Series
    Industrial 8-Port Managed Redundant Ethernet Switch

    • Turbo Ring with fast recovery time of 300 ms
    • Rapid Spanning Tree Protocol (IEEE 802.1w) supported
