Description

A DIgSILENT/PowerFactory bidirectional data interface conversion device

technical field

The utility model relates to the technical field of data conversion alarm prompts, in particular to a DIgSILENT/PowerFactory bidirectional data interface conversion device.

Background technique

With the expansion of the power grid scale, the power system becomes more complex. To conduct simulation analysis on power system scheduling and operation, electric power workers often need to analyze and process large-scale power grid data with the help of power analysis software, often in the data There are many problems in the input, storage, and output links. In the face of increasingly complex power system grid architecture, network parameters, experience-set parameters, and access to renewable energy, etc., it is currently necessary to develop devices that can solve the above problems. Now The data formats of various power system analysis software are different, and a single power system calculation software can no longer meet the needs of power research and analysis. With the development of power system analysis methods and computing technologies, the scale of the power grid has expanded, and a large number of data processing and analysis, a single power system calculation and analysis software to manually input data and change data is a large workload, and it is prone to errors. The safe and reliable operation of the power grid It involves the weight of the national economy, which urgently requires us to solve the above problems.

DIgSILENT/PowerFactory software includes almost all commonly used power system analysis functions, such as AC/DC power flow calculation analysis, fault analysis, protection analysis, reliability analysis, distribution network optimization and low-voltage network analysis, etc. The powerful simulation analysis of DIgSILENT/PowerFactory software and the comprehensive model library of power system components are favored by the majority of power researchers, but the data conversion between DIgSILENT/PowerFactory software and external power system analysis software such as BPA and reactive power optimization, etc. The conversion method is usually manual conversion or writing a corresponding data conversion program through specific data. In the era of large power grids and big data, manual input/output of data is time-consuming and labor-intensive and prone to errors. If there is an error in the input, it is difficult to find the location of the wrong data in the face of a large number of data files. Writing the corresponding data conversion program through specific data is aimed at specific power grid data, and the generality and scalability of the program are not strong.

However, when a breakpoint occurs in the data conversion process of the existing two-way data interface conversion device, because there is no corresponding breakpoint alarm prompt, the staff does not know whether the converted data is complete. Due to breakpoints in the process of data conversion, the integrity of the converted data will be affected. If the staff knows the breakpoint of data conversion, then the staff can choose whether to start the data conversion from the breakpoint record or completely restart the conversion according to the integrity of the data, which will improve the integrity and conversion efficiency of data conversion. is of great significance.

Utility model content

The utility model provides a DIgSILENT/ PowerFactory two-way data interface conversion device, if a breakpoint occurs during the data conversion process, the device will give a breakpoint alarm prompt in time, which is convenient for the staff to monitor and understand the integrity of the converted data.

In order to achieve the above object, the utility model adopts the following technical solutions:

A DIgSILENT/PowerFactory two-way data interface conversion device, including a data conversion processor, also includes a NAND gate circuit and an alarm circuit; the alarm circuit includes a buzzer, a current limiting circuit, a freewheeling inductance L and a switch circuit; the buzzer One end is grounded, the other end of the buzzer is connected to one end of the current limiting circuit, the other end of the current limiting circuit is connected to one end of the freewheeling inductance L, the other end of the freewheeling inductance L is connected to one end of the switch circuit, the switch The other end of the circuit is connected to the power supply, the control terminal of the switching power supply is connected to the output terminal of the NAND gate circuit, the converted data input terminal of the data conversion processor is connected to an input terminal of the NAND gate circuit, and the input terminal of the data conversion processor The breakpoint recording output terminal is connected with another input terminal of the NAND gate circuit.

The alarm circuit of this scheme controls the conduction of the switch circuit through the low level of the NAND gate circuit, and then the switch circuit controls the on-off of the buzzer to realize the alarm, thus prompting the staff whether there is a breakpoint during the data conversion process Appear. When the two input terminals of the NAND gate circuit receive the conversion data input signal and the breakpoint recording output signal from the data conversion processor at the same time, the output signal of the NAND gate circuit is a low-level signal of 0. The low-level signal makes the switch circuit conduct, so that the buzzer starts and sends out a breakpoint alarm prompt sound. When the output signal of the NAND circuit output terminal is a high-level signal of 1, the control terminal of the switch circuit receives a high-level pulse signal, the switch circuit is disconnected, and the buzzer is automatically turned off. If a breakpoint occurs during the data conversion process, the device of this solution will give a breakpoint alarm prompt in time, which is convenient for the staff to monitor and understand the integrity of the converted data.

The alarm circuit of this scheme controls the conduction of the triode Q1 through the low level of the NAND gate circuit, and then the triode Q1 controls the on-off of the buzzer to realize the alarm, thereby prompting the staff whether there is a breakpoint during the data conversion process Appear. When the two input terminals of the NAND gate circuit receive the conversion data input signal and the breakpoint recording output signal from the data conversion processor at the same time, the output signal of the NAND gate circuit is a low-level signal of 0. The low-level signal turns on the triode Q1, which in turn makes the alarm circuit turn on and emits an alarm prompt sound. When the PNP transistor Q1 base inputs a low-level pulse signal, the Q1 saturation conduction buzzer starts; when the PNP-type transistor Q1 base inputs a high-level pulse signal, the Q1 cut-off buzzer automatically turns off. When high voltage occurs in the alarm circuit, the current limiting circuit will limit the current passing through the buzzer to protect the buzzer. If a breakpoint occurs during the data conversion process, the device of this scheme will give a breakpoint alarm prompt in time, which is convenient for the staff to monitor and understand the integrity of the converted data.

In this scheme, when the trigger receives a low-level signal, the signal at the input terminal of the trigger is the same as the signal at the output terminal of the trigger, and the trigger sends a low-level signal to the data conversion processor’s data conversion selection trigger control terminal, so that the data The conversion processor converts the data to be converted from the record breakpoint, that is, when the signal is 0, the data is converted from the record point, which can greatly improve the efficiency of data conversion while ensuring data integrity . When the flip-flop receives a high-level signal, the signal at the input end of the flip-flop is opposite to the signal at the output end of the flip-flop, and the flip-flop sends a high-level signal to the data conversion processor's data conversion selection trigger control end, allowing the data conversion processor to All the data that needs to be converted are converted, that is, when the signal is 1, the data is converted from the beginning to the end, and the data is not converted from the recording point. In this way, if an error occurs during the conversion process, it can be converted from the beginning to the end to ensure the integrity of the data.
