| titleOfInvention | Calculation method for ground parameters of neutral point of hydraulic generator |
| abstract | The invention discloses a method for calculating the ground parameters of a neutral point of a hydraulic generator, which comprises the following steps: in the parameter calculation of the mode of grounding by parallel connection of the inductor on the load resistor at the low voltage side of the distribution transformer by using the neutral point of the hydraulic generator, the reactance X of the load resistor of the grounding transformer is introduced R ' three-phase earth capacitance C of earth transformer w Single-phase earth capacitor C of generator F Short-circuit impedance Z of grounding transformer k Four factors, namely calculating the ground parameter resistance R of the neutral point of the hydraulic generator 1 ' and inductance X 1 The value of' obtains a grounding mode of the neutral point which is counted with the four factors and connected with the reactance in parallel through the low-voltage side resistor of the distribution transformerThe parameter calculating method of (1). The method can be more accurate in parameter selection of the hydro-generator neutral point in a combined grounding mode, and avoids the increase of fault current caused by the error of parameter selection, thereby providing a choice for judging whether grounding variable reactance and three-phase grounding capacitance of the transformer are included in the parameter selection in the future. |
