Objectives and methods
Comprehensive power monitoring, control and energy analysis
Produce analytics about energy use to support decision-making for both immediate and future improvements
Skyworks has been an ETAP customer since 2019 with an electrical digital twin of their facility electrical system used for analysis at the medium voltage level. Their existing power system analysis with ETAP had already developed electricity and gas efficiency plans that resulted in 29,173 tons of CO2 reduction over these years. They recognized that they could do even more to improve system efficiency and reliability, and set out to advance their existing monitoring system by including medium and low voltage operations, and implementing predictive simulation to more quickly spot and resolve issues to reduce downtime.
Products used
ETAP Power System Monitoring & Simulation (PSMS) – Real-time power management system to determine the appropriate system response to a variety of changes and disturbances by using electrical and physical parameters, loading and generation levels, network topology, and control logics to locate the source of potential problems and advise on corrective actions to avoid interruptions, including:
ETAP eSCADA – Electrical network visualization, analysis and real-time data acquisition with customizable HMI viewers and notification systems including alarm, event, trending and tabular views, including:
ETAP Power Simulator – To create and customize a single-line diagram representing the electrical digital twin of the power system, including both medium and low voltage equipment, for use with load flow analysis in predictive simulation and real-time power monitoring.
What we delivered
One of the primary features that Skyworks required for this project was the ability to analyze potential scenarios by using ETAP Validate before Operate in order to reduce the probability of operator error during operation and maintenance activities. When an operator needs to perform changes in the operation and maintenance, such as breaker operations, motor starts, generator operations, loads transfers or more, they can simulate and validate the response of the electrical network and understand risks to avoid unforeseen conditions such as faults with voltage, frequency, protection system operations and power quality issues.
ETAP provided a comprehensive power monitoring, simulation and analysis solution of the electrical systems in a single environment, with full control over modeling design, simulation to operational maintenance. Integration with their existing management system was essential for Skyworks, whose primary objective was to increase the energy efficiency of the operation through operating data insights, integrated analytics and access to technical data that includes their entire electrical assets.
An ETAP real time server was introduced to manage and communicate with their existing metering and protection equipment using Modbus communication protocols, and to assist with event analysis, system trending and reporting a historian server was added that will archive real time and event historical data.
Operators were then able to use ETAP eSCADA templates and dashboards to customize their HMIs. In addition to the standard alarms provided in other SCADA systems, the ETAP system provides continuous electrical system analysis on the entire network, including non-monitored components, digitally. This increased the visibility of their entire electrical system, providing greater reliability and situational awareness of their operations. The power management system generates analytical alarms for every component in the network without any programming or extra configuration. ETAP eSCADA provides monitoring of metering and protection equipment for various manufacturer equipment. This result is a model-driven electrical SCADA with real time visualization through an intelligent graphical user interface with web-based dashboards and one-line diagram monitoring. As well, user-definable reporting for energy efficiency monitoring and KPI management were also defined and implemented.
Outcomes
Skyworks has been manufacturing integrated circuit modules since 1969, investing in technology, facilities, and state-of-the-art equipment, yielding a world-class operation based on advanced processes and a highly trained workforce. As one of the largest employers in the Mexicali region with 3100 employees, Skyworks was in need of an accurate way of controlling the energy costs of all their plant processes. Skyworks has already been using ETAP Digital Twin for their electrical system at the medium voltage level for the last 5 years, and this contributed to electricity and gas efficiency at plants that resulted in 29,173 tons of CO2 reduction over the years. In the semiconductor manufacturing business, it's very important to monitor the electrical system throughout the plant, including medium and low voltage operations. In this demonstration, you’ll learn how Skyworks expanded their ETAP model to include low voltage equipment, including predictive simulation in order to improve the reliability of their entire electrical system, and power system modeling (PSMS) to manage and ensure the electrical system power quality and increase the energy efficiency of their entire electrical operation.
