“…Finalmente, en especial por las propiedades de los sensores utilizados y por la naturaleza de la señal, recomiendan como mejor opción el análisis de la presión. Tomando en consideración que el bombeo profundo tiene una frecuencia que está dentro de los 5 a 15 Hz dependiendo de las geometrías implicadas [43], se propone realizar un estudio espectral de la señal mediante Fourier. Así, cuando el bombeo ocurre se tiene que las frecuencias preponderantes en la señal son la de bombeo y la de apertura y cierre de las válvulas del motor.…”

“…This model was further developed by Fink et al (1992) in order to include the dynamic of the rotating shaft connecting driver and compressor. Gravdahl and Egeland (1999) proposed a further modification by expressing the torque of the compressor as a function of shaft rotational velocity and mass flow rate while Gravdahl et al (2002) proposed to use the torque of the driver as input variable of the model instead of the rotational shaft speed . This last model was the reference for this work and was modified according to Morini et al (2007) in order to include also the recycle loop.…”

This paper proposes a control system for integrated pressure and surge control of centrifugal compressors for enhanced oil recovery application. The proposed control system is based on linear model predictive control. A fully validated non-linear dynamic model was developed in order to simulate the operation of the compressor at full and partial load. The model of the compression system includes a main process line with the compressor and a recycle line with the antisurge recycle valve. Different disturbance and control tuning scenarios were tested and the response of the model predictive controller was analysed, evaluated and also compared with a traditional control system. Temperature effects have been taken into account in the model of the process and in the constraint formulation of the MPC optimization problem. The results show that the proposed control technique is able to meet the process demand while preventing surge and also minimizing the amount of gas recycle.

“…The test system records status data of the compressor under different work conditions. By calculating the characteristic curve through that data and comparing the curve with the designed parameters, the performance of the impeller can be effectively evaluated [1] [2]. Fig.1 shows the general structure of the system.…”

Abstract-This paper presents a framework of prototype compressor impeller auto-test system. Two type performance test can be held in a unique pipeline layout. Work conditions are accuratly under control. Status data is acquired synchronously and precisely. Performance evaluation is accomplished efficient. This framework is proved to be highly available to improve traditional manual test method. I. INTRODUCTIONCompressors are critical equipments in many industries. The performance of the impeller, which is the core component of a compressor, directly infects the performance of the entire compressor. Therefore testing a prototype impeller plays an important role in the compressor industry.The traditional manual test method is a time-consuming job and the accurancy of test results depends on the skill and experience of the operation crew. In this paper, we present a framework of building an automatic test system to accomplish the test.Structure of the auto-test system is introduced in Part II. Part III shows a test flow and differences form the traditional manual test flow. As a conclusion Part IV summarizes the advantages of employing the auto-test system and presents further plans to improve this system.
