Mô phỏng công nghệ hóa học và dầu khí - Unit 10: Cause and Effect Matrix

Nhóm Mô phỏng Công nghệ Hoá học và Dầu khí Trường Đại học Bách khoa Hà Nội Dynamic Modeling using UniSim Design Unit 10 Cause and Effect Matrix Workshop Add a Cause and Effect Matrix to the simulation 2 Objectives Understand the use of the Cause and Effect Matrix 3 Cause and Effect Matrix  This unit operation replicates a Cause and Effect matrix commomly used in designing and operating the safety system of many processing plants.  It takes Inputs called Causes and sends Outputs called Effects  Each Input generate either a Healthy(1) or Tripped(0) state  The output is a boolean variable (1 or 0) which results from processing one of the Cause and Effect Matrix colums, and then any orther object in the simulation may read or use this value. 4 Cause and Effect Matrix  It is important that you clarify the 1 and 0 covention of the Cause and Effect Matrix for Healthy/Tripped, On/Off, Start/Stop...  For both the inputs and outputs a result of 0 indicates Tripped a result of 1 indicates Healthy  When the Invert checkbox is turned On a result of 0 indicates Healthy, a result of 1 indicates Tripped 5 Matrix Element  X – Trip  R – Reset  T – Time Trip  C – Coincident Trip  P – Permissive  I – Inhibit  S – Standby 6 Adding the C&E Matrix 1.
