It is following that the utility model solves the technical scheme that its technical problem adopted:
A kind of remote data acquisition and supervisory control system that is applied to the regional power grid idle work optimization is made up of the collection of reactive power compensation node data and monitor terminal, communication network and Surveillance center's three parts.
1, the reactive power compensation node data is gathered and monitor terminal
Collection of reactive power compensation node data and monitor terminal are installed in the electrical network scene; Gather the electric parameter of compensation node in real time through voltage transformer (PT) summation current transformer (CT); Through calculation process form three-phase voltage, three-phase current, three-phase is idle (gain merit) power, power factor, frequency, the data such as (idle) electric weight, real-time time and switching value state of gaining merit; And further whether judgment data is normal; Under normal state, regularly real time data is sent through the GPRS module, pass to Surveillance center, as occur sending warning message to Surveillance center immediately unusually through communication network; Simultaneously, receive and carry out the control command of sending from Surveillance center in real time, and carry out operations such as corresponding data re-transmitting or change switching value state according to control command.
2, communication network
What communication network adopted is GPRS network and Internet network synthesis communication solution, and the GPRS communication module sends to Surveillance center to data through GPRS network through Internet, and receives the control command information of sending from Surveillance center; Surveillance center inserts remote data acquisition and the monitoring that the Internet net realizes the scene is compensated node with the method for dynamic territory analyzing with dynamic IP addressing.
3, Surveillance center
Surveillance center mainly realizes communicating by letter with the GPRS communication module, accomplishes on the one hand and handles and the historical data at each terminal is managed gathering the data, the warning message that transmit with monitor terminal, in time assigns control command; For the user visualization interface is provided on the other hand; The statistics of the total looks of real-time display monitoring system, equipment running status, warning message, analog quantity and quantity of state; And can show with ruuning situation and the relevant index parameter of forms such as curve chart or form with the reactive power compensation node, let the user stay indoors and just can understand the ruuning situation of distant place equipment intuitively.
The utility model compared with prior art has the following advantages:
1, adopts the GPRS data communication terminal of advanced technology, perfect in shape and function, simultaneously, adopt the dynamic territory analyzing technology, the stability and the fail safe that have improved system works.
2, utilize the GPRS wireless packet data transmission technology and the Internet communication technology; And Surveillance center adopts the access way that inserts the Internet net with dynamic IP addressing; Make remote data acquisition point and the Surveillance center can real time communication, have higher real-time.
3, communications portion adopts transparent mode to transmit data, and therefore, the utility model can be used for other remote monitoring, monitoring system, has versatility and extensibility.
4, Visual calculation machine software, specialized data processing query capability provides functions such as powerful storage, analysis, form, curve, realizes data acquisition, wireless transmission and analyzes integrated automatically.
5, the result after the data processing inserts database automatically, and issue and Updating Information on network in time makes things convenient for user's remote browse, lets the home-confined ruuning situation that just can understand distant place equipment intuitively of user.
