By studying the current status and distribution system ground fault phenomenon and propose a solution, so that a more safe and reliable operation of distribution network, in order to provide our clients with high-quality electricity services
Based on the wireless radio online misoperation of currently existing offline misoperation cannot detect the device status, cannot really defend "go blank" as well as online misoperation construction complex, electromagnetic interference and other abuses, raised based on wireless communication online proofing of the operating system. The system provides real-time, accurate detection device status, the full "anti-go empty", the construction of a simple, non-interference. The proofing system for promoting safety, reducing construction complexity has a very important significance.
With the gradual recognition of the public harmonic problems,to evaluate the power system and the user's level of harmonic emitted on the point of common coupling has became a vital standard of the division of responsibility of the two parties. At home and abroad for the evaluate methods of the level of harmonic emission mainly focus on the system and user’s harmonic impedance estimates to start. However, due to the load, grid parameters and system operation are continuous alterative, the methods which based on element parameters and harmonic impedance calculation is still not mature enough.In this article bring forward the method for assessing harmonic emission level based on binary linear regression. Under the conditions of harmonic voltage and current stable (smooth harmonic) on the point of common coupling, the measurement parameters of harmonic current and voltage on the point of common coupling as the observation data, as the regression equations which be deduced by the system and user equivalent circuit to approach the harmonic impedance of system lateral.

With the harmonic problem of public importance on the gradual, in the public connection points on the power system and the user's level of harmonic fired a reasonable assessment of the division of responsibilities has become critical to both standards. At home and abroad for the launch of the level of harmonic estimation methods mainly focus on the system and user estimates of harmonic impedance to start. However, due to the load, grid and system operation parameters of the continuous changes in parameters of system components based on harmonic impedance calculation method is still not mature enough.
In this paper, based on binary linear regression method to estimate the harmonic impedance in the public interface of harmonic voltage and current stable (smooth harmonic) the conditions, the public interface of harmonic current and voltage measurement parameters for the observation data, and users of the system equivalent circuit of the regression equation derived lateral strike system harmonic impedance
Along with to takes seriously gradually to the public electrical network overtone question, carries on the reasonable appraisal in the public junction to the electrical power system as well as user's harmonic emission level, becomes the bilateral responsibility to divide the very important standard. Domestic and foreign mainly revolves regarding the harmonic emission level's estimate method to the system and the user overtone impedance estimate launches. But because shoulders, the electrical network parameter as well as the systems operation unceasing change, not was too still mature based on the system element parameter's overtone impedance computational method. this article proposes based on the dual linear regression overtone impedance estimate method, in public junction harmonic voltage, electric current basic stable (steady overtone) under the condition, take the public junction harmonic current voltage measurement parameter as the observation data, according to system and user equivalent circuit inferential reasoning regression equation seeking system side overtone impedance
