Power System Simulator for Engineering (PSS®E—often written as PSS/E) is a software tool used by power system engineers to simulate electrical power transmission networks [1] in steady-state conditions [2] as well as over timescales of a few seconds to tens of seconds.
Transmission lines are subject to thermal limits (simple megawatt limits on flow), as well as voltage and electrical stability constraints. The simulator must calculate the flows in the AC network that result from any given combination of unit commitment and generator megawatt dispatch, and ensure that AC line flows are within both the thermal ...
Output data (line condition, ratings and forecasts) are proprietary and confidential. To ensure provisions of data confidentiality, integrity and availability, the utility and the vendor implement secured communications with cyphering, access control and restrictions. Industry trends favor deployments in SaaS (software as a service) mode ...
The resistance and conductance contribute to the loss in a transmission line. The total loss of power in a transmission line is often specified in decibels per metre (dB/m), and usually depends on the frequency of the signal. The manufacturer often supplies a chart showing the loss in dB/m at a range of frequencies.
The analysis of lossless lines provides an accurate approximation for real transmission lines that simplifies the mathematics considered in modeling transmission lines. A lossless line is defined as a transmission line that has no line resistance and no dielectric loss. This would imply that the conductors act like perfect conductors and the ...
Examples of estimated bandwidth of different antennas according to the schedule VSWR and return loss by the help of the ANSYS HFSS [1]. Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys.
The AC transmission line is used for transmitting the bulk of the power generation end to the consumer end. [5] The power is generated in the generating station. The transmission line transmits the power from generation to the consumer end. High-voltage power transmission allows for lesser resistive losses over long distances in the wiring. [5]
a double circuit transmission line; two generators; a bus bar. Non-credible (also called "out-of-range") contingencies are not used in planning, as they are rare and their effects are hard to predict, for example, failures of: [4] an entire electrical substation; a transmission tower that carries more than two lines.
