Description
Technical Field
The application relates to the technical field of testing of control protection devices in direct current converter stations, in particular to a message encoding method and device based on an FT3 protocol.
Background
In a dc transmission system, a converter station is usually set up to convert ac power into dc power or vice versa and to meet the requirements of a power system for safety, stability and power quality. The converter station is provided with a direct current control protection device, the direct current control protection device receives signals transmitted by the voltage current transformers, and whether each voltage current transformer can normally operate or not is judged according to the signals. In order to realize the function, it is necessary to ensure that the dc control protection device can normally work, and in practical application, a test system is usually used to detect whether the dc control protection device can normally work, that is, the test system is required to simulate a voltage current transformer in the converter station to transmit a signal to the dc control protection device.
In a converter station, a traditional voltage current transformer is arranged, and an analog quantity signal is transmitted to a direct current control protection device; there is also a photoelectric voltage current transformer, which transmits digital signals to the dc control protection device, and the digital signals are generally digital messages under the FT3 protocol. In a converter station project, due to the fact that different suppliers of photoelectric voltage and current transformers exist, the provided FT3 protocol is different, the FT3 protocol has the characteristics of privacy and protocol variety diversity, and the requirements of high sampling frequency and high transmission rate are met, so that great difficulty is brought to field detection of a direct current control protection device.
At present, due to the characteristics of privacy and diversified protocol formats of the FT3 protocol, no test system can meet the output simulation function of the FT3 protocol of the converter station, or only individual protocol simulation can be realized, and diversified simulation of different protocols cannot be met. A certain manufacturer makes flexible and direct diversified protocols into a template library, but the converter station has multiple projects and multiple types of protocols, and the template library can only be suitable for the FT3 protocol which is tested and changed in data format and cannot be suitable for the untested FT3 protocol. Therefore, there is a need for a digital analog converter that can be applied to different types of protocols, so as to transmit the analog digital to the dc control protection device to detect whether the dc control protection device can work normally.
