Quantitative comparison and logical judgement are two main simulation methods used in DTS for the simulation of protection relay and security automatic equipment. From the view of DTS development, the quantitative comparison method is more difficult. From the view of DTS engineering application, two sets of fixed values corresponding to the two simulation methods bring a mass of work in fixed value setting and maintenance, and largely limit the practicality of DTS. In order to simplify the DTS development and application, this paper analyses the different characteristics of the main equipment protection, line protection, bus protection and security automatic equipment, and furtherly gives a choosing principle of simulation method for protection relay and security automatic equipment. Finally, this paper suggests that logical judgement method can be used in dynamic simulation.
