Modern offshore wind farms rely on SCADA system to manage information and ORG GF QUICK ROLLED OATS issue commands.One current interest and the future trend of SCADA is to have openness of working environments.The present paper follows the concept, and proposes the solutions to wind farms DMZ storing the wind data for internet guests and to firewall traffic control by utilizing the advantage of IEC 60870-5-104 protocol.The paper demonstrates the IEC 60870-5-104 protocol packets, routes, and packet structural changes in major octets after passing each network component.

Two results are shown.The first result is in the plot, the wind speed value against the packet number.By managing the packet number and selecting proper packets, the classification/privatibility of wind speed values released can be regulated by the wind farm administrators to decide the quantity Pads and batches of packets to be stored in DMZ for internet guest, as well as for the firewall to set up traffic flow.The second result is the figure of all data traffics in the networks.

It displays that the proposed solutions for data traffic flow control works effectively under the situation of limited bandwidth but enormous number of packets, and opens out a latitude for future study.The purpose of this paper is to develop the openness of SCADA working environment and to assist wind farm SCADA administrators to optimize the management skills, from the IEC 60870-5-104 protocol packet point of view.The author declares the present paper is invented independently and personally, to avoid any infringement of intellectual properties and patents.
