DISCRETE CONTROL FOR INTERCONNECTED POWER SYSTEMS IN ENERGENCY CONDITIONS

3 u m o a r y

In this paper a power control algorithm baaed on the second Lyspuney ■ethod has been suggested.

Digital techniąues are predlstlnated to these functions as the microcom-puter can be programmed to solve the mathematical whlch deflne the desired control operatlon.

Authors descrlbe a digltal control deslgned for this purpose.

The easy control law baaed on the deriratle of the Lyapunov functlon along the faulted system has been deweloped. Application of this lew lead to determination of the value and slgn of the controlTector.

Influence of Talue wariatlonBt load demand, sensltlwlty zones, regula-tlon constants and the clearing tlme la dlscussed.

Concluslon are presented as results of system dynamie responsea lllustra-ting the Influence of control aystems on warlatlons of this factors.
