Electrical submersible pump (ESP) operation is compromised by free gas, resulting in premature pump failure and production losses in new wells. It is essential to detect the onset of abnormal operations. We develop a model that predicts abnormal ESP operation when the free gas level increases in the pump. The model compares operation parameters with the parameters of normal operating ranges; it shuts down the ESP when necessary. We used a Schlumberger PIPESIM software (version 2017.01) to perform nodal analysis technique; we tested the model using the other multiphase correlation model and field case studies (where the gas problem in ESP was reported). We employ a homogenous model to calculate the differential pump pressures at various gas volume fractions. Nodal analysis of the intake and discharge point predicted the commencement of abnormal ESP conditions and the associated parameters (critical gas fraction, minimum operating pump intake pressure, and pump discharge pressure). The model results were similar to other surging correlation models (e.g., Romero, Dunbar, Turpin, Cirilo, and Zhou models); they were also identical to field case studies. We identify three performance stability phases when an ESP is exposed to free gas. These are the normal and abnormal operating ranges, as well as the ESP shutdown condition. Modeling permits careful monitoring of ESP operations that can be compromised by free gas.

“…Since a standard FBG has a length of approximately 7-10 mm, the length of the piezo component should be at least 20 mm to allow for installation of additional FBG supporting arms [17].…”

“…Strain proportional to the input voltage is imparted to the FBG by the piezoelectric stack. The MVT construction ensures twofold strain amplification [17]. To avoid the piezoelectric component depolarization and permanent damage its nominal voltage was chosen to be 1 kV as mentioned earlier.…”

“…As can be seen, the higher fields are moved away from the piezo thanks to the electrodes with a diameter 3 times larger than the diameter of the PIC181 component. Also, designing the electrodes and the ceramic arms rounded with a 1 mm radius helped to minimize the electrical stress around the components with different dielectric constants and further improve the electric field distribution [17]. The field in the component is nearly 0.6 kV/mm which is well below the 2.5 kV/mm limit for the material.…”

This paper considers the design of a fiber-optic voltage sensor for applications in the field of wide area monitoring, protection and control of high voltage power networks. The proposed 132-kV sensor, combining a capacitive voltage divider (CVD) and an optical medium voltage transducer (MVT), was theoretically evaluated through software simulations and its expected performance was assessed based on the operational requirements specified by the IEC standards for electronic voltage transformers. The simulation results suggest that the sensor, when fabricated, should be capable of meeting the requirements for metering and protection classes specified by the IEC 60044-7 standard.

“…Advantages that optical, and specifically fiber-based sensors, offer to high voltage electric systems include: light weight, high dielectric strength, and electromagnetic interference immunity, among others (Bohnert et al, 2005;Chen et al, 2011;Lee, 2003). These properties make optical sensors very attractive to new developments and implementations for power delivery, measurement and control operations in power systems and high voltage situations (Fusiek et al, 2012;Yang et al, 2019). Potential instrument transformers, namely current and voltage instrument transformers, are one of the most critical elements in measurement and control of electric power in substations, generation plants, transmission, and distribution systems (Sawa et al, 1990).…”

This paper proposes a highly simplified optical voltage sensor by using a piezoelectric bimorph and a Fiber Bragg Grating (FBG) that can be used for high voltage applications with a relatively good accuracy and stability. In this work the theoretical framework for the whole opto-mechanical operation of the optical sensor is detailed and compared to experimental results. In the analysis, a correction term to the electric field is derived to account for the linear strain distribution across the piezoelectric layer improving the designing equations and giving more criteria for future developments. Finally, some experimental results from a laboratory scale optical-based high voltage sensing setup are discussed, and shown to be in excellent agreement with theoretical expected behavior for different voltage magnitudes.
