Alarm System for EAST Poloidal Field Power Supply

The poloidal field (PF) power supply is an important subsystem of the EAST (ExperimentalAdvanced Superconducting Tokamak as the device status detection and protection are essential. The PFpower supply monitor system is based on the Experimental Physics and Industrial Control System andthe human machine interface is the Control System Studio (CSS). The alarm is a plugin of CSS, used tohelp operators take correct action at the correct time. This technical note creates the alarm system,including server, client, Java Message Service interface, and relational database and configures thealarm attribute and sets the action for all variables that may trigger the alarm. When the alarm istriggered, the system goes into fault mode, the alarm server sends mail or pops up a windowautomatically to prompt operators, and some actions may be executed automatically to protect thedevice. Then operators solve the fault according to the guidance and the system returns to normal,realizing device status monitoring and protection in real time. The EAST experiment shows the alarmsystem has better function and stable performance.
