| description | The invention discloses a water turbine runner damage detection method based on guide bearing parameters, and relates to the field of water turbine fault detection. The method aims at solving the problem that at present, whether a water turbine is damaged or not cannot be judged according to changes of external characteristics of the water turbine, and serious associated accidents occur. The method comprises the steps of collecting upstream and downstream water level actual values, a unit output actual value, an upper guide bearing throw actual value, a lower guide bearing throw actual value and a water guide bearing throw actual value under the stable operation working condition of the water turbine; obtaining a theoretical value vuT of an upper guide bearing, a theoretical throw value vdT of a lower guide bearing and a theoretical throw value vgT of a water guide bearing under corresponding working conditions according to the installation condition of a shaft system of the water turbine generator set, the o |
