Problems solved by technology
[0002] At present, due to the superiority of integration when the switchgear contact temperature measurement device and the protection measurement and control device are used in the same place, the first is to integrate the two in terms of physical structure, which can save some space in installation and use management. It can also bring convenience to users; but the core of integration is the integration of functions, that is, the integrated design of the integrated device from the perspective of program processing; otherwise, the functions of the two are still independent of each other, and resources such as internal plug-in chips are also separated. This kind of integration can only be regarded as a relatively simple physical assembly, not a comprehensive integration in the true sense. The result is still troublesome device use, high component cost, inconsistent data structure, scattered functions, independent hardware and many other disadvantages

Embodiment Construction
[0016] A method for temperature measurement and protection control, based on a hardware platform that integrates a temperature sensing module into a relay protection module, uses the original data processor of the relay protection module to process temperature and protection measurement and control data, the measurement and control data of the present invention Temperature and protection control methods, the specific steps are as follows figure 1 The flowchart shown:
[0017] a), system initialization, then simultaneously enter step b), step d);
[0018] b), sequentially judge whether the temperature signal value converted from the temperature signal 1, temperature signal 2, and temperature signal 3 sent by the first, second, and third temperature sensing probes is greater than the first preset value: if any temperature The temperature signal value converted from the temperature signal sent by the sensing probe is greater than the first preset value, and enter step c); if the...

The invention provides a method for controlling temperature measurement and protection. A temperature and an electric value are used as measuring sources with the same property and processed in a mode fully equivalent to that of remote measurement, and judgments on temperature measurement and protection are made, so that functions, such as uniform event information, storage information, alarm driving, protection outlet, human-computer interface, communication interface and the like can be realized. Temperature measuring and controlling treatment is fully integrated to logic flow treatment, so that protection measurement control of a comprehensive temperature function truly integrated in a seamless mode is realized and the defects of troublesome use, non-uniform data structure, divergent function and the like in the prior art can be effectively overcome.
Description
technical field [0001] The invention relates to a temperature measurement and protection control method integrated with a temperature measurement module in a relay protection device in a power system.
