Abstract

The invention discloses a third-generation intelligent transformer substation analog quantity in-place module test system and an application method thereof. The system comprises a power supply module,a mainboard module, an HSR message communication module, a current amplifier module and a voltage amplifier module installed in a chassis. The power supply module is separately connected to each module, and the mainboard module includes a D / A conversion module, an HSR message parsing module, a central processing unit, a monitoring module and a host computer communication module which are sequentially connected, and the application method is to realize sampling precision and dispersion testing, sampling response time testing and maintenance mechanism function testing of the analog in-place module. The system and method of the invention can realize the batch automatic detection of the function and performance of the analog in-place module, realizes the HSR protocol analysis simulation of the analog in-place module, and provides a new way for the automatic testing and maintenance of the function and performance of the analog in-place module. The maintenance and repair efficiency of intelligent transformer substation can be increased and the safe and efficient operation of the power grid can be ensured.

Description

technical field [0001] The invention relates to a third-generation intelligent substation analog on-site module testing technology, in particular to a third-generation intelligent substation analog on-site module testing system and an application method thereof. Background technique [0002] Since the State Grid Corporation started the pilot construction of smart substations in 2009, up to now, about 5,000 smart substations have been built in China, including the first generation of smart substations and the second generation of smart substations. Due to the high degree of system integration and reasonable structural layout, smart substations have achieved certain results in economical, energy-saving and environmental protection. However, in actual use, many problems have also been exposed. Especially in the operation and maintenance of smart substations, the heavy maintenance workload and high maintenance costs greatly restrict the development of smart substations. In ord...

AI Technical Summary

Problems solved by technology

[0003] At present, the analog on-site module of the third-generation smart substation is a new thing, and there are the following problems in operation and maintenance: (1) The analog on-site module is used to realize the acquisition, transmission and control of analog information such as voltage and current. The "hands" and "feet" of the intelligent control of the entire substation, but for the operation and maintenance personnel, the primary equipment module is equivalent to a "black box"

At the same time, because the analog on-site module adopts the new HSR ring network communication protocol, there is a lack of relevant testing methods and testing equipment in China, which greatly responds to the safe operation of substations

(2) The analog on-site module has a wide range of application scenarios, the number of applications is huge, and the workload of inspection personnel is heavy. Whether batch automatic inspection can be realized has a great impact on the efficiency of transportation inspection
