Problems solved by technology
[0004] The invention provides a state monitoring system of a hydroelectric generator and a method for optimizing the associated relationship of a governor. The collected operation data of the unit is comprehensive and comprehensive, which can effectively evaluate the operating state of the unit, and solve the problem of only considering the unit when determining the associated relationship in the prior art. Active power or only when the swing value exceeds a certain threshold, the operating condition of the unit is considered to solve the problem that the data collection of the association relationship in the existing technology is too rough to keep the unit running in the best condition.

Embodiment Construction
[0029] The present invention will be further described in detail below with reference to specific embodiments.
[0030] Aiming at the defects of the existing technology for optimizing the coupling relationship of the governors of the axial-flow rotary-slurry hydro-generator set, the present invention provides a hydro-generator state monitoring system and a method for optimizing the coupling relationship of the governors, aiming to solve the problem of determining the coupling relationship in the prior art. Only consider the active power of the unit or only consider the operating condition of the unit when the oscillation value exceeds a certain threshold value when connecting the relationship, so as to solve the problem that the data collection of the existing technology is too rough to keep the unit in the best condition. operating conditions.

The invention discloses a hydro-generator state monitoring system and a governor joint relation optimization method thereof, and belongs to the technical field of hydropower stations. The state monitoring system comprises a plurality of monitoring points which are arranged on the hydro-generator set and used for obtaining the comprehensive operation condition of the set, and a control unit of the state monitoring system scores the measured value of each monitoring point according to a scoring model and calculates the score value of the comprehensive operation condition of the generator grid-connected set in real time. And after receiving the unit comprehensive operation condition analog quantity, the speed regulator control unit combines the active power value of the unit to perform weighting to obtain a score value at a certain joint relation point, and selects the point with the highest score value as the optimal point of the joint relation. According to the method, the unit operation condition obtained by the state monitoring system is quantified to participate in determination of the unit governor joint relation, so that the joint relation obtained by the governor is close to the optimal joint relation to the maximum extent, and the unit can always operate under the optimal condition.
Description
technical field [0001] The invention relates to the technical field of hydropower stations, in particular to a state monitoring system of a hydroelectric generator and a method for optimizing the association relationship of a governor. Background technique [0002] Under normal circumstances, there is a one-to-one correspondence between the opening of the guide vane and the opening of the paddle of the axial-flow rotary paddle hydro-generator set under different water heads, and this relationship is the cooperative relationship of the governor. Under the best cooperative relationship, the opening of the guide vane and the opening of the propeller reach the best cooperation state. At this time, the flow state of the water flowing through the guide vane and the propeller is the most stable, and the vibration and swing values of each part of the unit are the lowest. , the operating efficiency of the unit is the highest. However, the synergistic relationship of the governor o...
