Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0038] A kind of prime mover and its speed regulating system model online checking method of the present invention, comprises the following steps:
[0039] Step (1) Obtain the real-time operation data and key control parameters of the checked prime mover and its speed control system.
[0040] The prime mover includes a steam turbine, a water turbine, and a gas turbine, and the speed regulating system of the prime mover includes two parts: a governor and an actuator.
[0041] Set up a collection device near the prime mover and its speed control system. The collection device can be a single independent screen or placed in other screen cabinets. The governor and actuator of the turbine are equipp...

The invention discloses a prime mover and a speed regulation system model online checking method and system thereof. The method comprises the following steps: obtaining real-time operation data of a checked prime mover and a speed regulation system thereof; acquiring an actual measurement model of the checked prime mover and the speed regulation system thereof; checking the collected real-time operation data and an output result of the actual measurement model to obtain a check result of the prime mover, the speed regulation system of the prime mover and the actual measurement model of the prime mover; and obtaining a calculation model of the checked prime mover and the speed regulation system thereof, and checking an output result of the calculation model and an output result of the actual measurement model to obtain a double-model checking result between the calculation model and the actual measurement model of the checked prime mover and the speed regulation system thereof. The method can comprehensively judge whether the actually running prime mover and the speed regulation system thereof, the actual measurement model and the calculation model are abnormal or not and locate theabnormal position.
Description
technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an online checking method and system for a prime mover and its speed regulating system model. Background technique [0002] As the core equipment of the power plant, the prime mover and its speed control system ensure that the generator set provides stable and continuous power to the grid. The primary frequency regulation of the generator is an important measure to ensure the stable operation of the power grid. However, due to equipment abnormality, equipment parameter modification, unit aging and other reasons, the performance of the prime mover and its speed regulation system will change, resulting in insufficient primary frequency regulation capability of the generator, and the frequency stability contribution provided by the power grid is reduced when there is a major disturbance, seriously Threats to the safe and stable operation of the power grid.
