The design of remote discharge scenario management system on EAST

摘要

The discharge scenarios on EAST plasma control system (PCS), characterized by different waveform parameters and different hardware requirements, will need a systematic discharge scenario management system for remote and local operators, in order to optimize storage structure and rationally manage discharge time. The remote management of discharge scenarios will require extending the functionalities of the present PCS "future shot" and "next shot" modules. Taking advantage of database technique, the operators can acquire detail information of all discharge scenarios directly without PCS user interface and search the specified scenarios by key words. In addition, the system can elect optimal scenarios automatically based on discharge schedule and plasma pulse setting for later artificial selection. To this purpose, a new remote discharge scenario management system (RDSMS) basis for Web is being conceived on EAST. The system contains a database with functions of "user management", "scenario verification", "prepared scenario management", "actual discharge scenario management" and "discharge schedule management". This paper will present the relevant conceptual design and give an account of the test results for implementation on EAST discharges. (C) 2016 Elsevier B.V. All rights reserved.
