FIG. 1 is a step diagram of a method for custom alarming of a centralized control center monitoring system of a river basin step power plant according to an embodiment of the present invention.
Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1, the embodiment of the invention provides a user-defined alarm method for a centralized control center monitoring system of a river basin step power plant, which is used for processing alarm signals sent out in the process of monitoring a managed step power plant by the centralized control center of the river basin step power plant, and displaying the processed alarm events on a display interface of the centralized control center monitoring system to warn operation and maintenance personnel.
Referring to fig. 1, the method for self-defining alarm of the centralized control center monitoring system of the river basin step power plant according to the present embodiment includes the following steps:
s1, acquiring a generated alarm signal;
s2, confirming the alarm state of the alarm signal obtained in the step S1, and judging whether the obtained alarm signal is an alarm event requiring alarm or an operation event requiring no alarm;
s3, dividing alarm levels of the alarm events acquired in the step S2 according to the emergency degree of the alarm signals, wherein the alarm levels comprise emergency stop, emergency alarm, important alarm and general alarm, and the emergency degree of the alarm signals corresponding to each alarm level is different;
s4, displaying the operation event acquired in the step S2 and the alarm event of each alarm level acquired in the step S3 on a display interface respectively.
The working process of the user-defined alarm method for the centralized control center monitoring system of the river basin step power plant provided by the embodiment is as follows: firstly, an alarm signal sent by a monitoring system of a centralized control center of a river basin step power plant is acquired, then the alarm state of the alarm signal is confirmed, the alarm signal is firstly divided into alarm events needing to be alarmed and operation events needing no alarm, then the alarm events are divided according to the emergency degree of the alarm signal and the preset alarm level, the alarm signals are divided into emergency stop, emergency alarm, important alarm and general alarm according to the alarm level, different alarm levels correspond to different emergency degrees of the alarm signal, finally the operation events and the alarm events of all alarm levels are displayed on a display interface respectively, so that the complicated alarm events are distinguished on the display interface, an operation and maintenance person can intuitively acquire the alarm event with high emergency degree from the display interface, the important alarm event is avoided, the operation and maintenance person can quickly find and process the alarm event, and the alarm event processing efficiency is improved.
Specifically, in this embodiment, the alarm signal is divided into an alarm event and an operation event, where the operation event is a normal operation condition of a generator set of the step power plant, so that in order to facilitate an operation and maintenance person to query the whole operation event to occur in a message, no alarm prompt is performed. The alarm event is divided into four alarm levels of emergency stop, emergency alarm, important alarm and general alarm from high to low according to the emergency degree, wherein the emergency stop level is the fault or defect of the generator set, when the generator set is in an abnormal running state, the emergency stop processing is directly carried out on the generator set, the generator set is ensured to develop to a worse condition, and when the monitoring system carries out the emergency stop alarm, the generator set usually has serious faults and accompanies the emergency stop process or accident stop process of the related generator set; the emergency alarm level is that the generator set has serious faults or defects, and the generator set is in an abnormal running state, at the moment, operation staff are required to carry out emergency treatment to temporarily stabilize the running state, and the generator set can be stopped in a normal stopping mode, otherwise, the condition that the generator set is in fault and stopped in a short time can occur; the important alarm is that the generator set has general serious faults or defects, and the generator set can continuously run after being processed or relevant safety measures are taken, or needs to be checked and processed in time after the machine is stopped; the general alarm is that a certain defect or fault occurs in the generator set, but serious consequences cannot be caused, operation and maintenance personnel need to pay attention to and monitor whether the generator set is reset or not, and related measures are not needed. The alarm emergency degree of the generator set under different running states can be effectively distinguished by adopting the distinguishing mode of the alarm signals, the alarm quantity can be effectively reduced and the alarm accuracy can be improved by customizing the alarm level of the alarm signals, so that operation and maintenance personnel can be helped to develop the operation monitoring work of the generator set, and the alarm level can be increased or reduced according to the actual requirements, so that the operation and maintenance personnel can quickly acquire the required information.
In this embodiment, step S20 is further included before step S2, where the running state of the generator set of the step power plant is confirmed to be a non-standby state, a transitional state or a grid-connected running state; step S2 further comprises the step of confirming the alarm state of the alarm signal obtained in step S1 under the current running state of the generator set of the step power plant, wherein the alarm states of the alarm signal are running events when the generator set is in a non-standby state, the alarm states of the alarm signal are alarm events when the generator set is in a standby state, the alarm states of the alarm signal are alarm events or running events when the generator set is in a transitional state, and the alarm states of the alarm signal are alarm events when the generator set is in a grid-connected running state. Because the same alarm signal has different alarm levels in different operation states of the generator set, part of alarm information belongs to normal conditions in the corresponding operation states, alarm condition determination is needed first during alarm, then alarm level division is needed, for example, the generator set outlet breaker is switched off, the alarm information is an operation event when the generator set is in a shutdown state, but the alarm information is an emergency shutdown level alarm event when the generator set is in the operation state, therefore, the operation state of the generator set needs to be determined first before the alarm event is distinguished from the operation event, and then whether alarm is needed or not is selected.
Specifically, when the generator set is in a non-standby state, namely, the generator set is in a state of fault processing, overhauling, defect processing and the like, overhauling operation or generator set action is carried out to cause that the related generator set alarms in a monitoring system to belong to a normal condition without monitoring, in the state, after the centralized control center confirms the state, the related generator set is abnormal or the fault is divided into running events in the monitoring system without alarming; when the generator set is in a standby state, the running state and the health level of the related generator set are required to be monitored, so that the abnormal or running parameters of the related generator set need to be processed in time when the related generator set is not in a normal range, otherwise, the condition that the generator set cannot be started and run normally can occur, after the centralized control center confirms that the generator set is in the standby state, the condition of the related generator set abnormal or fault is divided into alarm events in a monitoring system, and the alarm level is selected according to actual setting and then is given out to prompt operation and maintenance personnel to process in time; the generator set is in a transitional state, namely, when the generator set is started, stopped and tested, the abnormal state of part of the generator set or the abnormal operation parameters are normal, at the moment, the operation events and the alarm events need to be distinguished according to the actual operation conditions, the specific alarm level of the alarm signal after being divided into the alarm time is determined according to the operation state of the generator set and the influence range of the fault, and the alarm prompt operation staff can accurately process the alarm in time; when the generator set is in a grid-connected operation state, the requirement on safe and stable operation of the generator set is highest, so that the fault, abnormal movement or abnormal operation parameters of the related generator set are required to be timely subjected to alarm prompt, the alarm level of corresponding alarm information is relatively higher than that of other states, and after the centralized control center confirms that the generator set is in the state, the alarm level is divided according to the actual operation condition and the alarm information condition, and alarm prompt is carried out.
In this embodiment, step S0 is further included before step S1, and an alarm information base is established, where the alarm information base has a plurality of storage units, and each storage unit stores related information of an alarm signal, and the related information of the alarm signal stored in the storage unit includes a text description corresponding to the alarm signal, a generator set associated with the alarm signal, an operation parameter of the associated generator set, an operation state of the associated generator set, and a history fault defect and a history processing safety measure of the associated generator set. The alarm information base is used for storing relevant information of all alarm signals accessed into the centralized control center, the relevant information comprises a text description corresponding to the alarm signals, a generator set related to the alarm signals, an operation parameter of the related generator set, an operation state of the related generator set, a historical fault defect of the related generator set, a historical processing safety measure and the like, the text description of each alarm is consistent with the text description of the monitoring system during alarm, so that the centralized control center can automatically retrieve the relevant information from the alarm information base and display the relevant information during alarm, an operation staff can conveniently acquire the information of the current state, the historical fault and the like of the related generator set of the alarm, and meanwhile, the operation for processing the used alarm can be provided for the operation staff to refer to, the alarm processing efficiency is further improved, and the relevant information can be perfected according to actual conditions.
In detail, step S2 further includes matching the alarm signal acquired in step S1 with the relevant information of the alarm signal stored in the alarm information base. Step S4 also comprises the step of displaying the relevant information corresponding to the alarm signal on a display interface. After the alarm signal is obtained, the centralized control center can quickly find out the required information by matching the alarm signal with the related information of the alarm signal stored in the alarm information base, and the related information corresponding to the alarm signal is displayed on the display interface, so that the operation and maintenance personnel can conveniently check the information.
In this embodiment, step S4 further includes setting a popup window on the display interface, where contents displayed in the popup window are an operation parameter of the generator set associated with the alarm signal, an operation state of the generator set, a historical fault defect of the generator set, and a historical processing safety measure, and the contents are displayed in the same popup window or are displayed by multiple popup windows respectively. The occurrence of the alarm is caused by the faults or defects of the generator sets, namely, each alarm can be related to the corresponding generator set, the related content of the alarm signal is displayed on the display interface in the form of a popup window, and the popup window can automatically pop up after the alarm is sent out, so that operation and maintenance personnel can quickly know the fault condition of the generator sets through the popup window.
In this embodiment, step S4 further includes providing a plurality of alarm sub-interfaces on the display interface, where each alarm sub-interface displays one of an operation event and an alarm event of each alarm level. By arranging a plurality of alarm sub-interfaces on the display interface to respectively display the operation events or the alarm events of one alarm level, the operation and maintenance personnel can quickly acquire the alarm information, the related operation information and alarm processing information of the generator set, and the operation and maintenance personnel can conveniently select the alarm information with higher emergency degree for priority processing, so that the operation stability of the generator set is improved. The color of the alarm characters displayed in the alarm sub-interface is different according to different alarm levels, so that the emergency degree of the alarm can be distinguished quickly, or the characters in the alarm sub-interface flash until an operation and maintenance person confirms and then stops flashing, an alarm reset message can be displayed under the alarm independently, or the color of the alarm characters is changed directly, and the alarm characters are uniformly displayed in white characters after the alarm is reset, so that the operation and maintenance person can know the reset state of the alarm conveniently.
