Siemens offers a large portfolio of applications for the oil and gas industry. The solutions in the different fields demand very high reliability and availability of the electrical systems off-shore, on platforms or sub-sea, on-shore in refineries, pipeline systems, gas storage systems and in GTL- or LNG-plants.
Our long experience in studies for all kinds of industrial systems results in elaborated concepts for the design and operation of the electrical equipment. Overall plant concepts are designed, taking into account all severe fault and outage situations to minimize operational risks. A comprehensive analysis of the technical performance allows the optimization of the system configuration including technical performance and recommendation of countermeasures. The aim is to reduce risks, ensure personal safety and guarantee availability to produce a best practice solution for our customers.
Load flow and short-circuit investigations
Load flow and short-circuit studies are performed to support the optimum design of the electrical plant.
Harmonics and inter-harmonics
The analysis of the harmonic behavior of the system involves compensation, pf-correction, filter design
, investigation of risks from sub-synchronous resonances (SSR), the identification of suitable countermeasures as well as the optimization of the VSD control concept.
Dynamics of the electrical system
Dynamic studies of the electrical system may involve fault and outage analysis, an evaluation of the frequency stability, voltage recovery, generation stability and the impact of generation control.
Detailed design studies
In detailed design studies the sensitive behavior of the whole electrical system is simulated, including specific equipment like VSDs and all kinds of controllers. In particular, the interaction of control and the influence of harmonics and inter-harmonics are analyzed. With these studies the SSR risk can be minimized and recommendations can be made for control and suitable countermeasures.
Dynamics of the electrical and the steam system
These studies investigate the design of turbines, boiler and supplementary firing and aim at an improvement of the availability and reliability of the system.
Dynamics of the electrical system, steam system and process
Studies which involve an evaluation of the steam system and process focus on the optimization of the overall concept and an improvement of the control, management system, operation and reaction in emergency situations. These analyses can reduce energy costs, CO2 emission and maintenance costs and increase the availability and flexibility of the power system.
In protection studies the protection philosophy is defined. They provide recommendations for protection equipment and selective settings for all protection devices for generation, grid compensation and loads.
An optimization of the overall control system design of industrial power systems can increase system availability and reliability and reduce CO2 emissions and fuel consumption.
