Study on Remote Settings Modification of Automatic-Safety Device

Remote settings modification technology is one of the key study subjects to achieve integration of dispatch and control in power grid. It deserves a further study in ensuring the security and prevention of information distortion during the delivery to Automatic-safety device after modifying and operating the settings file. Currently, there are many methods to achieve remote settings modification. After studying and analyzing two common cases, an optimized remote settings modification technology based on the five levels of security defense mechanism is first developed; Then, the foundations for remote settings modification mode that include the exclusive format, exclusive setting platform and identity verification mechanism are detail introduced. By comparing two common cases, the result shows that application of optimized remote settings modification technology has highly flexibility and can efficiently reduce the difficulty and complexity for operators. Also, the operation security is improved by applying the five levels of security defense mechanism. In summary, the application of remote settings modification technology has better prospects.
