Intelligent startup and shutdown guidance strategy and system for huge hydraulic power plant

Abstract

The invention discloses an intelligent startup and shutdown guidance strategy for a huge hydraulic power plant. The method includes: firstly, obtaining startup and shutdown monitoring information of agenerator set; acquiring a system characteristic quantity of the monitoring information of the generator set according to the starting and stopping monitoring information; calculating a characteristic quantity data added value of the generator set system; and finally, judging whether the characteristic quantity data added value exceeds an alarm reference value or not, and if not, returning to thestep of obtaining starting and stopping monitoring information of the generator set again; And if the alarm reference value is exceeded, carrying out dynamic alarm reminding. According to the strategy, the starting and stopping monitoring and starting and stopping guidance functions of the generator set are realized; key links of the starting and stopping process of the unit are effectively and automatically monitored; information such as time consumption, trend change conditions and whether the state of an equipment measuring point is normal in each link of startup and shutdown is automatically displayed, whole-process monitoring and analysis of important measuring points are developed for working conditions such as the transient state and the steady state of startup and shutdown of a unit, problems of equipment in the startup and shutdown process are early warned, and the monitoring efficiency of operating personnel and the automatic startup and shutdown success rate of a power plant are improved.

Description

Technical field [0001] The invention relates to the technical field of guidance strategies for starting and stopping of hydropower plants, in particular to an intelligent starting and stopping guidance strategy for giant hydropower plants. Background technique [0002] At present, hydropower plants generally adopt sequential control methods to realize automatic start and stop of generator sets. Operators can only view the start and stop steps being performed through the start and stop process interface on the operator station, but they cannot visually monitor the generator set during the start and stop process. Whether the auxiliary equipment has been started and stopped according to the process, whether the start and stop time meets the requirements, etc., it is difficult for the operators to find abnormal conditions during the start and stop process, and the efficiency of the unit start and stop monitoring is low. [0003] Hydropower plants mainly determine the startup and shutdo...

[0002] At present, hydropower plants generally adopt the method of sequential control to realize the automatic startup and shutdown of generator sets. Operators can only view the ongoing startup and shutdown steps through the startup and shutdown process interface on the operator station, but cannot intuitively monitor the generator sets during startup and shutdown. Whether the auxiliary equipment has been started and stopped according to the process, whether the start and stop time meets the requirements and other information, it is difficult for the operator to find abnormal conditions during the
