The protection system of a four-terminal transmission line involves a high degree of complexity. Many devices, including protection and communication devices, are involved in providing optimal protection to the line in operation. The level of complexity is further increased when, as in the case described in this article, three companies with three different protection philosophies come together to protect such a line. This presentation will describe the commissioning test of the line protection of a four-terminal line. During the test, the responsible protection engineers used a system-based protection test to gain a detailed insight into the behavior of the protection system.

Over the years, the aircraft turbojet engine has evolved into one of the most intricate multivariable systems, pivotal in human transportation. It serves not only as a thermodynamic power converter but also as a constant arena for technological advancement. Achieving optimal control and addressing diagnostic challenges necessitates a comprehensive understanding of these engines' parameters and performance aspects. Often, critical technical details of jet engines remain elusive, with only limited information available in manufacturer catalogs. The primary challenge lies in calculating and extrapolating vital performance parameters, relying solely on data such as fuel flow, jet exhaust temperature, and turbine rotation speed. The impetus for this study stemmed from the need to investigate a recurring issue with several turbojet engines experiencing severe failures during operation. The turbine blades suffered extensive damage in each instance due to excessive heat exposure. The initial step in addressing these problems was developing a mathematical model and dynamic analysis of the turbojet engine. A transfer function for the turbojet engine was defined from operational characteristics and experimental test data. This transfer function described the turbine rotation speed as a controlled parameter, with fuel flow as the controlling parameter. Determining total gain and time constant parameters revealed them as nonlinear functions, primarily reliant on the turbojet engine's mechanical characteristics and thermodynamic processes. Subsequent to establishing consistent initial conditions, the simulation results were scrutinized and compared with experimental test data. In terms of dynamic behavior, this study underscores the high fidelity of the presented mathematical model for turbojet engines. The simulation results demonstrated a numeric accuracy exceeding 1.5%, highlighting the model's effectiveness in replicating real-world performance.

Summary: Built by the Army Corps of Engineers between 1933 and 1942, Grand Coulee Dam was the largest concrete structure in the world for decades. With the expansion of the third power station in 1974 made it the largest power plant in the world at the time. It still remains the largest power plant in the USA with a capacity of over 6 GW in three power stations. It also has a large pumped storage facility of several hundred MW that links to the Columbia Basin Irrigation Project. As the center-piece of the Columbia Basin Project, the dam's reservoir supplies water for the irrigation of 671,000 acres. Tour Summary: The tour will starts at 12:00 noon at the Visitor Center where we will receive a safety briefing. We will then get into USBR vans and head to the Banks Lake Headworks. From there kind of a driveby view of the BPA 230kV&500KV substations. We can't get out for security reasons. From there, travel to Crown Point for a great view of the dam and get out for pictures. We will travel to the 3rd power house which has recently completed generator and turbine refurbishments. We will go up to the top of the dam overlooking the spillway for pictures and then back to the vans and visitor center by 4:30. Visit Requirements: - This is a hard hat, VIP tour of an operating power plant so closed toe shoes and sensible clothing is required. Shorts, dresses, sleeveless shirts, tank tops, high heels are not permitted. - Photo ID is required for this tour. Unfortunately, US Citizens only due to time it takes to perform background checks. US citizens will be asked to provide a copy of their ID to the USBR at least one week in advance of the tour and will be required to present their driver’s licenses or valid ID the day of the tour. - No backpacks, fanny pack, bags, purses, etc., are allowed. Wallets fitting in a pocket are OK. Water will be provided along the way. - This is a technical tour for IEEE members and their quests. There is a shorter tour available for the public that may be more appropriate for others such as younger children. More info on the public tour can be found at http://www.usbr.gov/pn/grandcoulee/visit/tour.html - There is a significant amount of standing, walking and climbing stairs on this tour. - Photos are allowed in most areas of the tour. Restricted areas will be pointed out during the tour briefing. Agenda: Agenda 12:00 pm – Welcome and Introductions 12:30 pm – 4:30 Tour of the switchyard, Banks Lake Headwork, Coulee Dam and Powerhouses Highway 155, Grand Coulee, Washington, United States, 99116
