Classification alarm and identification auxiliary method of real-time production parameters of power plant

Abstract

The invention provides a classification alarm and identification auxiliary method of real-time production parameters of a power plant, and relates to the power system field. The prior art has the disadvantages that alarm is inaccurate and out of time, and measurement device and production device can not be identified, etc. The method is characterized by equipment groups of a turbo generator unit into two kinds namely production devices and measurement devices by connecting a production real-time system with the turbo generator unit, and performing classification alarm and identification according to a change rule of equipment parameters when the two kinds of devices are faulty. Various alarm ways and dynamic alarm fixed value are combined to alarm abnormal change of operating parameters asearly as possible so that operators can alarm early, find early and treat alarms as early as possible by reference to the change.

Description

【Technical field】 [0001] The invention relates to the field of power systems, in particular to an auxiliary method for classifying, alarming and identifying real-time production parameters formed by secondary development of a real-time production system in the production field of power plants. 【Background technique】 [0002] Turbogenerator sets have high-tech, highly automated, highly planned, and highly intensive equipment groups. In addition to the four main equipment of boilers, steam turbines, generators, and main transformers, a set of turbogenerator sets has thousands of sets Various rotating mechanical equipment, heat exchange equipment, transmission equipment, reflection processing equipment and their electrical control, automatic control, and operating devices are collectively referred to as production equipment below. There are tens of thousands of monitoring and measuring points reflecting the operating status of these equipments. The measuring device controls the...

Problems solved by technology

When the deviation between the setting value and the actual value is small, it may cause frequent alarms, and the reliability of the alarm will be reduced; sex not guaranteed

[0005] In order to avoid frequent alarms, the actual situation is that the alarm parameter setting value deviates greatly from the actual value, and early alarm cannot be achieved. The conventional alarm method based on this principle has the following disadvantages: the setting value is fixed, and the setting value deviates greatly from the actual value , unable to make a parameter trend alarm, after an alarm action, the function of alarming again will be lost; the procedures for modifying the setting value are cumbersome; manual intervention and reset are required after the alarm occurs; the optical plate alarm expansion capability is limited and the cost is high

When the steam turbine generator set is running, when a certain operating parameter is alarmed, it is not possible to identify whether it is a failure of the production device or a fault of the measurement device.

[0007] Because the alarm method is relatively backward, the quality of the current power plant operation monitoring mainly depends on factors such as the professional quality, sense of responsibility, and mental state of the operating personnel. The optical name plate still plays an important role in the operation monitoring process. To a certain extent, it affects the safe operation of the unit
