中文摘要 | 隨著電腦及通訊科技的發達,天然氣管線之儀控系統已進展為SCADA。但SCADA 僅能提供管線在 RTU 各點之即時資訊, 故我們無法獲知流量、壓力和溫度等變數在 整條幹管之分佈情形。 引入動態模式後, 即可大幅提昇 SCADA 系統之功能。 因即時模式 RTM 可計算壓力、流量等變數在整個管路網之分佈情形,其附屬模組可分析壓力及管存量等 ,且可偵測儀器之漂移及管路之洩漏。預測模式 PM 更是測試、調配、規劃和訓練等工作的 好幫手。 因此天然氣管線在安裝 SCADA 系統後,極值得考慮再加入這些線上和離線的動態 模式。 |
英文摘要 | Traditional SCADA system technology is being distributed to lower levels of the information network. SCADA can provide real time information about the pipeline, but only at the RTU's. The Real-Time Model (RTM) will provide information not only at the RTU's but also throughout the pipeline. This will allow for more effective control and operations of the pipeline. The Predictive Model (PM) provides the capability to simulate future pipeline system operations. It allows the user to change pipeline system conditions such as gas supplies and demands. The PM is also used for operator training purposes. |
