Description
Technical field
The present invention relates to pressure computer integrated protection in a kind of communication simulation type of simulated teaching training system.
Background technology
When l-G simulation test, giving middle pressure computer integrated protection by signal source state, signal source is much more expensive, and is intended in one to press computer integrated protection simultaneously.In simulated teaching training system; need to install pressure computer integrated protection in multiple stage; if being required for for signal; then need multiple stage programme-controlled signal source just can complete; cost is much more expensive, and compares and take up room, and the power of signal is also limited in certain scope; therefore the full simulation system with middle pressure computer integrated protection is built, almost extremely difficult.
Summary of the invention
In order to overcome the deficiencies in the prior art; it is an object of the invention to provide pressure computer integrated protection in a kind of communication simulation type; by field bus communication mode write protection data and measurement data; without programme-controlled signal source; abundant emulation data class; reduce the equipment cost of teaching simulation, improve the safety that equipment runs.
The purpose of the present invention realizes by the following technical solutions:
A kind of communication simulation type is pressed computer integrated protection provide two completely isolated RS485 communication interfaces; one communication interface is used for and background system communication; as data acquisition use, another communication interface for system to device write protection data and measurement data.
Preferably, protection data include protective current value, zero-sequence current value, protection magnitude of voltage, protection residual voltage, negative sequence voltage, voltage vector and, frequency etc..Measurement data includes current value, zero-sequence current value, magnitude of voltage, residual voltage, frequency, power factor, active power, reactive power etc., and device is calculated according to the data measured, and the cumulative sum carrying out energy data amounts to.
Preferably; when using device; transformer can connect and can not connect; primary circuit is without power supply; teaching simulation training system is by state carrying out power system computation according to current power system, and the result obtained is written in device by writing data-interface, and device is protected according to protection input state and protection definite value; and data result is shown as device data, and to background system communication.
Preferably; when building teaching simulation training system; article one, pressure computer integrated protection in the accessible multiple stage one communication simulation type of bus; including route protection, tranformer protection, mother, prepared auto restart, PT protection etc.; system gives different values to respectively according to power system computation result different devices, and entirety carries out the emulation of power system.
Compare conventional implementation, the beneficial effects of the present invention is:
The present invention replaces traditional mode gathering electric current, voltage to the mode of pressure computer integrated protection write data in a kind of communication simulation type by field bus communication mode; greatly reduce the construction cost of simulated teaching training system; and by the difference of write data, simulated teaching training subject can be completed.Simultaneously as major loop is without power supply, it is only necessary to the power supply of device own is powered, and this improves the electrical security of simulated teaching training process.And possess field-bus interface, pass through fieldbus, it is possible to by real time data, value data, status data transfers to background system, improve the level of IT application, it is possible to meet the requirement of the simulated teaching of modern teaching simulation training.
Accompanying drawing illustrates:
Fig. 1 is the application structure schematic diagram pressing computer integrated protection in a kind of communication simulation type of the present invention；
In figure: 1, background system computer；2, fieldbus (system data acquisition)；3, fieldbus (emulation data write)；4, pressure computer integrated protection (route protection) in a kind of communication simulation type；5, pressure computer integrated protection (tranformer protection) in a kind of communication simulation type；6, pressure computer integrated protection (prepared auto restart) in a kind of communication simulation type.
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
Background system computer 1 is communicated with pressure computer integrated protection 4,5,6 in a kind of communication simulation type by fieldbus 2; communication data includes electric real time data, electric state, electric energy, definite value etc.; background system computer 1 calculates according to electric logic; by fieldbus 3 to pressure computer integrated protection 4,5,6 data write in a kind of communication simulation type, the data of write include protection data and measurement data.
In a kind of communication simulation type press computer integrated protection 4,5,6 according to write data, be computed with logical judgment after, carry out protection act or action moved back in throwing, have the accumulation calculating carrying out electric flux of electric energy metrical function.
