According to the existing specifications, design shallow embedded column foot of 500kV self-supporting partially prestressed reactive powder concrete pole, and perform numerical simulation of column foot stress under actual working condition by using finite element analysis software ANSYS WORKBENCH. Results show that the mechanical characteristic of shallow embedded column foot is good. It can well transmit larger axial pressure, pulling resistance and horizontal force generated by top load of RPC pole. Through the simulation analysis we found that shallow embedded column foot has high safety reliable degree under operation condition, can be used in the current 500 kV transmission lines; In terms of construction technology performance, construction of shallow embedded column foot is simple and quick, can effectively reduce the complexity of construction, shorten the construction period.

This paper presents the design and development of a laboratory facility to accompany a three-course power systems sequence in the Energy and Power Engineering Technology program at Purdue University. This hardware-based system is modeled after the US electric grid and emulates a complete power network: generation, transmission and distribution, end-use, and control. The approach taken is to divide the lab hardware in two: a simplified three-phase, three-bus system for power transfer from a synchronous generator and infinite bus to a variable load, and a multi-bus single phase system with prime movers and associated generators, transformers, contactors, transmission lines, constant impedance loads, induction motor loads, power factor correction capacitors, DC generation, AC/DC conversion, energy storage, high voltage DC transmission, and supervisory control and data acquisition. The bifurcation of the lab hardware by phase enables the hands on teaching of both three-phase power basics and more advanced content in context of the power grid, supporting a systems-based approach to electric power engineering education.
