This paper describes the design and construction of a new 3000-hp single-shaft gas turbine which has been designed for sufficient speed flexibility to make it ideal for mechanical drive applications. Over-all performance and efficiencies of the gas turbine are presented together with a description of the control system and its application to variable-speed drives. A simplified electrohydraulic control system is described which retains necessary protective features and minimizes the accessory equipment. Particular emphasis has been placed on refinery applications where reliability is paramount.

Acceleration And Deceleration

The paper proposes an algorithm for control of processes based on variable-speed drives with low acceleration and deceleration rate of the motor, which determines the dynamics of the whole control system. The results of investigation of the controller based on the proposed algorithm are presented and discussed. The controller provides good transient performance of the control system response in case when the drives with different motor acceleration and deceleration rates are used.

System Effectiveness

In centrifugal compressor installations that use a variable speed drive such as gas turbine, speed control is an effective method of controlling capacity. Compressors are normally protected from surging by an antisurge control loop which recycles the discharged gas to the suction of the compressor. In an upset condition which results in flow reduction, the two controllers may interact whereby performance of the surge controller may be compromised. In this paper, a dynamic simulation technique is used to illustrate the interaction.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor. Software and hardware used in thisthesis work are DCS CENTUM VP Yokogawa.
