Abstract

Abstract: In recent years, the operation ultra-high voltage(UHV) AC projects in China has brought about new challenges to the effective control of automatic generation control system. Digital simulation is an effective means for system analysis. But in the full dynamic simulation program, no control strategy model is suitable for UHV tie-line. In order to dynamically simulate the active power control of the 1 000 kV UHV AC tie-line between the north China power grid and the central China power grid, a new T standard-based automatic generation control(AGC) strategy model is proposed based on the T standard - the AGC performance assessment standard, the controlling requirements of the UHVAC tie-line and field operational experience, the CPS control strategy model, the product of the UHV AC tie-line bias and the area control error(ACE), and the characteristics of the product in the receiving-end system and the sending-end system. The new model is achieved in the full dynamic simulation program (PSD-FDS) and is proved to be effective through simulation case study based on field data. The result of the case study confirms that the T standard strategy has better effectiveness than the CPS standard strategy.

Key words: UHV, tie-line, automatic generation control, active power control, strategy model, dynamic simulation
