Study On The Influencing Factors Of 1000MW Turbine Generator In Leading Phase

1000MW turbine generator has very important significance for ensuring the power grid to be security and stability.The construction of modern power grid has appeared a trend of ultra-high voltage,large capacity and long-distance transmission.Residual charging power will appear on circuit when transmitting power is in excess of natural power,witch need to be absorbed in the ends of the circuit.Millions of kilowatt generators has very important significance for adjusting reactive power of the power grid.The study of 1000MW generators in leading phase ability in this paper has accumulated very valuable experience and data for the operation of the large capacity and high parameter.First,this article researches 1000MW in the theory of leading phase ability operation and analyzes the static stability limit of generator In the case of the AVR,the generator is not involved in the operation of the generator and the AVR is involved in the operation of the generator,and it is derived from the specific formula,which is the work of the AVR in the generator,which is the work of the generator,and it indicates that external reactance is an important factor in the static stability of the generator.Finally,the static stability boundary curve of generator is obtained.On this basis,the restriction relationship between the generator's reactive power and generator terminal voltage and system voltage is calculated by using the equivalent circuit diagram of the system,and the voltage limit of the voltage of the generator is calculated by using the high voltage bus and the factory,and the normal operation of the generator terminal voltage shall not be lower than 26.6kV.In special cases,the problem of low voltage of high voltage bus bar in the factory can be solved by adjusting the main transformer and the high transformer subsjunction of the factory.Meanwhile,the problem of the voltage limitation of low voltage bus in the factory with the adjustment of the low variation sub and other related measures is proposed.Then without considering in phase and taking into account the influence of the influence of two kinds of cases of G60 will be type microcomputer type protection setting value calculation,it is concluded that the asynchronous impedance characteristics not action specific values.Through the field practice,this article researches the difference between the single generator leading phase and double generator leading phase,the tactics of allocating idle work and static stability in the double generator leading phase.On this basis,this article provides the graph of working condition in the double generator leading phase.
