    With the advent of automatic loading of large generator units, it becomes necessary to establish safe and reliable limits for rates of change of loading. The most economical and practical way of determining such limits is by field testing the units in question. This paper describes the instrumentation and test techniques presently used by Philadelphia Electric Company to determine these rates. Eco... View full abstract»

    The Bull Run supercritical unit was simulated by a linearized mathematical model based entirely on physical laws and design data, using an approach verified by comparison of an earlier simulation with field tests. A large set of differential and algebraic equations was solved to obtain transient responses. These responses were matched by transfer functions to obtain a process model which represent...

    A method is presented for finding the response of a large power system to cyclic load variations. The waveform of the load variation is represented as a Fourier series. The power system is represented by a set of first-order, linear differential equations. These are solved to give the response of the system to each harmonic component, and the results combined to give the total response. Results fr... View full abstract»

    The error adaptive control computer (EACC) permits new and different degrees of freedom for automatic control. It is a logic computer which monitors the control error signal and makes logical decisions on how much, if any, control action should be taken depending on the characteristics of the error signal. Control action may be reduced to any judiciously chosen minimum by adjusting the EACC to dis... View full abstract»

    The methods of adjustment and operation of the governors of hydraulic turbine generating units, in attempting to meet conflicting requirements, have occasionally developed over the past decade in directions different than would be suggested by the rapidly developing science of control. The most prominent factors contributing to the divergence have been the obscuring of proper speed control for ind... View full abstract»

    The Routh-Hurwitz criterion and the D-partition method are used in the steady-state stability study of a synchronous machine connected to an infinite bus bar. The machine has a continuously acting voltage regulator and a speed governor. The effects of the saliency and the short-circuit ratio of the synchronous machine, and that of the tie-line resistance and reactance on the stability of the syste... View full abstract»

    A 100-machine transient stability program has been developed which represents the effects of machines much more completely than has been available previously. Both d-and q-axis quantities are fully represented and saturation effects in both axes are incorporated. The speed-governing and voltage-regulating systems available are extensive and complete, thus allowing a very close approximation to any... View full abstract»

  • Direct Calculation of Power System Stability Using the Impedance Matrix

    The impedance matrix combined with the Norton equivalent and some loads as fixed impedances serve to reduce the number of buses that must be carried in high-speed computer memory. Noniterative techniques are used to gain speed and a Thevenin equivalent is used to check out-of-step conditions of individual machines. Representations of induction motors, generators (salient and nonsalient), govemors,... View full abstract»

    Earlier successful topological methods of determining the steady-state currents and voltages throughout any lumped-parameter electrical network are extended to include solution of the transient current and voltage response caused by switching in or out and, in any sequence, direct, alternating, or impulse-voltage sources in any branch of the network.

    The usual two-reaction theory of synchronous machines yields results that neglect to take saturation into account. Based on a method developed in a companion paper [1], the radial airgap induction is found in synchronous machines when supplying balanced loads. The armature currents are considered to be distributed uniformly in the upper and lower layer of the armature windings. The partial differe... View full abstract»

    The current unbalance in a 50O-kV double-circuit and a 138-kV triple-circuit, paralleled and untransposed transmission line is analyzed comprehensively. This paper establishes that the magnitudes of individual circuit current unbalances due to currents circulating between the paralleled circuits are more significant than the net through system unbalance. Since the former were not considered in pre... View full abstract»
