DTS中继电保护和安全自动装置仿真方法的分析

定值比较法和逻辑比较法是调度员培训仿真系统(DTS)的2种主要仿真方法。从系统开发来讲，定值比较法比逻辑比较法难度更大；从工程应用来讲，2种仿真方法对应的2套定值给定值整定和维护带来了极大的工作量，成为影响DTS实用化的重要的制约因素。为了简化DTS的开发与工程应用，文中针对主设备保护、线路保护、母线保护及安全自动装置的不同特点，分析了不同的继电保护和安全自动装置仿真方法的选用原则，并分析了逻辑比较法在动态仿真中的应用。

STUDY ON THE SIMULATION METHODS OF PROTECTION RELAY AND SECURITY AUTOMATIC EQUIPMENT IN DISPATCHER TRAINING SIMULATOR (DTS)

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.
