Abstract
The invention discloses a method for judging oil leakage and pressure fluctuation of a hydraulic station. The method includes the steps that a liquid level sensor and a pressure sensor are used for measuring the liquid level value and pressure value of the hydraulic station in real time, and the measured liquid level value and pressure value are joined into a PLC analog input channel; moreover, Siemens configuration software WINCC is utilized for filing the liquid level value and pressure value; maintenance personnel can calibrate an alarm system according to a historical filing curve of the hydraulic station during stable operation; and the oil leakage and pressure fluctuation of the hydraulic station can be judged from the aspect of 'rate of change' and the aspect of 'cumulant', and accordingly instantaneous monitoring alarm and historical monitoring alarm are carried out separately. The method is more comprehensive, timely and effective compared with a pure 'threshold' alarm judging method. The instantaneous monitoring alarm value and historical monitoring alarm value used by the system are obtained by analyzing plenty of WINCC filing curves through long-term calibration, and the method has higher adaptability and reliability compared with a common method using empirical values.
Description
Technical field
The present invention relates to field of hydraulic station, particularly relate to a kind of method judging Hydraulic Station leakage of oil and pressure oscillation.
Background technology
Leakage of oil and pressure oscillation are the accidents the most easily occurred in Hydraulic Station running, and Hydraulic Station makes for a long time
During with, between existing due to the pressure differential produced when liquid flows in Hydraulic Elements and pipeline and each element
The reasons such as gap, often can produce leakage.Hydraulic system is once revealed, it will cause system pressure to set up
Do not get up, the most also can cause environmental pollution, have a strong impact on the production efficiency of enterprise.The most general way is
Utilize liquid level sensor and pressure sensor to measure liquid level and the force value of Hydraulic Station in real time, then it is set one
Individual threshold value, when having exceeded this threshold value, i.e. reports to the police to hydraulic system.If set threshold value is appropriate,
This method can play good effect.But at present setting to threshold value has the biggest empirical, if setting
Fixed improper, false alarm can be produced, cause corresponding device misoperation, often run counter to desire.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and provide a kind of and accurately judge Hydraulic Station leakage of oil and pressure wave
Dynamic method.
The present invention for achieving the above object, by the following technical solutions: a kind of judge Hydraulic Station leakage of oil and pressure wave
Dynamic method, it is characterised in that comprise the following steps:
(1), utilize liquid level sensor to measure the liquid level of Hydraulic Station in real time, utilize pressure sensor to measure liquid in real time
The force value at pressure station；
(2), the liquid level measured and force value are accessed PLC analog input channel, and utilize process monitoring
Liquid level and force value are filed by systems soft ware；
(3), warning system is carried out liquid level and the instantaneous monitoring alarm value of pressure and the mark of history monitoring alarm value
Fixed；
(4), system liquid level and the pressure of Hydraulic Station are carried out instantaneous monitoring alarm and history monitoring alarm respectively,
The step of instantaneous monitoring alarm is: 1. master control system to each in Hydraulic Station running concrete time
Between point calculate liquid level and the undulate quantity of pressure in certain time；2. by liquid level and the pressure of this time point calculated
The undulate quantity of power compares with the instantaneous monitoring alarm value of system calibrating；3. the biggest when undulate quantity
When instantaneous monitoring alarm value, then send warning message；
The step of history monitoring alarm is: 1. master control system starts to record its running from Hydraulic Station stable operation
In total level fluctuation amount and pressure wave momentum；2. by record total level fluctuation amount and pressure wave momentum be
The history monitoring alarm value that system is demarcated compares；3. history monitoring alarm it is both greater than within a certain period of time when undulate quantity
During value, then send warning message.
As preferably, the process monitoring system software in described step (2) is Siemens configuration software WINCC.
As preferably, liquid level in described step (3) and the instantaneous monitoring alarm value of pressure and history monitoring report
The demarcation of alert value is the filing curve by analyzing substantial amounts of process monitoring system software, and is demarcated by long-time
Obtain.
The invention has the beneficial effects as follows: the present invention in terms of " rate of change " and " cumulant " two to Hydraulic Station
Leakage of oil and pressure oscillation judge, carry out instantaneous monitoring alarm and history monitoring alarm respectively, compare simple
Judge to report to the police with " threshold value " more comprehensive, timely and effective.Native system use instantaneous monitoring alarm value and
History monitoring alarm value is by analyzing substantial amounts of WINCC filing curve, and is obtained by long-time demarcation,
For comparing the general method using empirical value, there is higher adaptability and reliability.
