Dynamic Security of Interconnected Electric Power Systems – by Mohamed EL-Shimy

By Mohamed EL-Shimy

This ebook is written for engineers enthusiastic about the operation, and regulate of electrical strength platforms. The booklet additionally presents info and instruments for researchers operating within the fields of strength procedure safeguard, balance, operation and keep an eye on. It contains volumes. within the first quantity, the normal options for balance and dynamic equivalence are offered. moreover, an outline of the most drivers and standards for modernization of the conventional tools for on-line purposes is mentioned. the second one quantity comprises advances within the safeguard, balance, regulate, and stabilization of electric strength structures. The given fabric is written in graded complexity for facilitating their inclusion in undergraduate, postgraduate, and technical education classes. For on-line dynamic safety structures, a big a part of this quantity comprises the derivation, research, and stabilization of the SMIB equivalence of energy platforms. This quantity additionally comprises the operation and dynamical features of variable renewable strength iteration (wind and solar-PV) in addition to their dynamical interactions with strength platforms and the interconnection necessities are offered in information.

19) The function D() takes the form shown in Fig. 11. It is depicted from the figure that the damping increases with the increase of the power angle till a power angle of 90o. Afterward, the damping declines. It is known that the maximum allowable steady state power angle of an uncontrolled cylindrical pole machine is 90o; higher angle values cause instability of the machine. In most types of power systems studies, the average value Dav of the damping coefficient is used instead of representing the actual variations of the damping coefficient.

In addition, the impact of various quantities on the system performance is demonstrated. The system linearized model is implemented on the simulink as shown in Fig. 20. The following cases are considered. Fig. 20: The simulink model of the linearized dynamic model of the SMIB system of the numerical example – the machine is represented by the classical model 37 M.
