Description
Technical field
The utility model is related to electric power supervisory control fields, and in particular to a kind of electric power monitoring system multi-mode reminds dress
It puts.
Background technology
Since implementing regulation and control integration with State Grid Corporation of China, transformer equipment operation Centralized Monitoring business has included electricity
In net scheduling unified management.Meanwhile as the rapid development of electric system, the quantity of substation sharply increase, it is linked into regulation and control
The power network signal that central monitor system carries out Centralized Monitoring is even more that exponentially increases again, and therefore, monitoring post is for power grid security
The importance of stable operation is more and more prominent, and monitor will not only be responsible for the remote control operation of transformer substation switch, but also will
Centralized Monitoring is carried out to all transformer equipment operating statuses in compass of competency.Simultaneously as the particularity of power supply industry and again
The property wanted, equal Attended mode when small of power system monitor job position request 24, under the monitoring operation of such high intensity, monitor is easy to tired
Labor, and due to the effect of biological clock and daily rhythm, in the time-division in morning, people is easy to energy and laxes, cause monitor for
The perception of power network signal declines, so as to enough could not timely respond to locate to some transformer equipment accidents or abnormal signal
It puts, adds safe operation of electric network hidden danger to a certain extent, therefore it is most important to develop a set of effective monitoring and reminding device.
Power system monitor signal be broadly divided into accident, it is abnormal, out-of-limit, conjugate, inform five classes, wherein trouble-signal belongs to a kind of
Signal, such as equipment fault tripping, abnormal, out-of-limit signal belong to two class signals, conjugate, inform that signal belongs to three classes signal.First,
Two class signals belong to the signal that monitor needs key monitoring.When power network signal occurs, protective device or observing and controlling by equipment
Device sends specific power network signal to grid monitoring system, and different classes of power network signal appears in the difference electricity of monitoring system
In net item window, signal of the monitor in item window come judge the seriousness of accident abnormality occurred and influence model
It encloses.
Nowadays, for the mutual cooperation in working, power grid regulation center monitoring person and dispatcher are in same hall
Work, monitor are mainly the speaker voice prompt that is connected by the screen display on monitoring system backstage with cable to carry out letter
Number monitoring, i.e., when power network signal occurs, signal is shown in power grid item window, at the same can in the form of voice prompt to supervise
Control person is informed that monitor removes the power network signal in browsing item window after voice informing is heard, to confirm every power grid
Whether signal can influence power network safety operation.
Above-mentioned pattern possesses following shortcoming：1. indicating mode is single, flexibility is poor, and warning effect is limited；2. reliability
It is not high, there is certain security risk；3. long-time audio alert may make dispatcher and monitor's distraction, influence to electricity
The judgement of net signal.
The reason for causing disadvantages mentioned above is：
1. since dispatcher and monitor work in same hall, in order to avoid influencing each other, general voice reminder
It all only repeats 1-2 times, easily misses prompting；
2. only voice reminder mode is too single, it is impossible to while meet the needs of different monitoring scene, different monitoring person；
3. if voice module damages, can not repair immediately；
4. due to the influence of biological clock and daily rhythm, work long hours makes monitor relatively hold plus shift work mechanism
Fatiguability, it is impossible to ensure that monitor is keeping spiritual high concentration all the time, the easy rhembasmus within the specific period,
Monitor will decline the susceptibility of voice reminder at this time；
5. dispatcher and monitor's routine work are heavy, alarm sound easily makes dispatcher and monitor's distraction, increases
Add security risk.
