結合國內石油集輸行業的特點，對長輸管道（站庫）的SCADA系統進行了探討，首先對SCADA/OPS系統進行簡要分析，包括控制器的硬件構成、常規的通信方式和其特點比較等。然后對系統功能的中心站功能、現場站功能和系統輔助功能等進行了闡述。最后在系統安全上，主要對INTERNET和INTRANET接入進行了重點分析包括和風險評估等。
Over the past few years, most companies with critical infrastructure controlled by SCADA, DCS,
and other process control systems have taken the approach to group all of their real-time
systems in an environment called the PCN or process control network, and try to keep that
environment as separate and isolated as possible from the IT and corporate networks. While this concept is a move in the right direction, treating the PCN environment like a black box and trying to manage one firewall or cyber defense solution at the border with IT is not adequate to protect from changing external and internal threats. The sensitive nature of the PLC and DCS devices controlling the critical infrastructure assets require a higher level of network segmentation and advanced defense solutions not currently recommended or available through most security firms and IT vendors.
This white paper takes a look at the fundamental issues with the current practice of securing
SCADA and control systems, introduces the concept of security zones of vulnerabilities, and
briefly introduces several new and unique cyber defense solutions that can be deployed at each
security zone.
This paper discusses some of the options available to companies concerned with the threat of cyber attack on their critical infrastructure, who as part of their process of tightening up security, wish to prevent unauthorized network access to SCADA systems that monitor and control critical infrastructure.

IEC TC57所推出的IEC 870-5-1和IEC 870-5-2關于遠動系統內數據傳輸的標準構成了DNP V3.00數據鏈路層的基礎，DNP 3.0規約使SCADA進行有了國際標準規約。標準規約的適用面廣，功能強大，可以大大減少電力網維護的工作強度。饋線終端單元（FTU）是配電自動化系統中的重要組成部分。
