The construction of Tuas Power Station started in the mid 1990s. The plant has steadily grown to be a significant player in the competitive Singaporean electricity market. Stage One of Tuas Power Station is equipped with the country's largest steam generators which are capable of producing 600 MW each.

Unified operator interface solution enables remote operation

The CENTUM CS 3000 / UOI was selected for this project. The control platform in the UOI is the GE Fanuc CIMPLICITY Human Machine Interface (HMI) system, which fully integrates the controls for the turbine and BOP auxiliaries and uses the same screens/formats at both the turbine and BOP HMI displays. The CIMPLICITY HMI used in the UOI is a SCADA based design that fully supports the customer's requirement for remote operation capability.

At the age of approximately 30 years the plant underwent $A 72 million technology upgrade in 2001, to improve operating reliability and performance. Macquarie Generation, Yokogawa Australia and Ralph M Lee concluded an alliance agreement to supply and install the replacement control system at Liddell.

インバーターで回転機を制御する製造過程では、設備の故障が製品品質や生産に影響を及ぼし、振動センサによる監視も、インバーターで回転数が変わるためしきい値の設定しての管理が難しくなっています。広域モニタリングシステムとAIの組合せで改善します。

省エネに重要な電力や蒸気の使用量を計測しエネルギー監視。構内に分散した設備でそれぞれに監視している場合、全体把握が難しくなります。広域モニタリングシステムはデータ集約・レポート作成で見える化し、全体としての優先改善ポイントの把握など、効率化をサポートします。

スチームトラップの点検には専門知識と機材が必要であり、目視だけでは詰まりなどの不具合を捉えにくいです。また、高所や危険区域にある場合、点検頻度の低下や不具合の発見が遅れることがあります。これらを手軽に遠隔監視するソリューションをご紹介します。
