In recent years, microelectronic components are more widely used in relay protection devices, but most of the electronic devices are electronic sensitive devices, which are easy to be affected by interference. When the relay protection devices are interfered in the power system, if there is a fault, it will affect the overall security of the power grid, resulting in the power grid cannot operate stably. When the interference energy exceeds the maximum allowable energy of the logic circuit, it will directly damage the components and affect the normal operation of the relay protection device. Therefore, strengthening the anti-interference ability of relay protection and automation devices has become an important topic in power system. 展开更多

A novel operation control method for relay protection in flexible DC distribution networks with distributed power supply is proposed to address the issue of inaccurate fault location during relay protection,leading to poor performance.The method combines a fault-tolerant fault location method based on long-term and short-term memory networks to accurately locate the fault section.Then,an operation control method for relay protection based on adaptive weight and whale optimization algorithm(WOA)is used to construct an objective function considering the shortest relay protection action time and the smallest impulse current.The adaptive weight and WOA are employed to obtain the optimal strategy for relay protection operation control,reducing the action time and impulse current.Experimental results demonstrate the effectiveness of the proposed method in accurately locating faults and improving relay protection performance.The longest operation time is reduced by 4.7023 s,and the maximum impulse current is limited to 0.3 A,effectively controlling the impact of large impulse currents and enhancing control efficiency. 展开更多

The article discusses the possibility of further modernization of the standard microprocessor relay protection of AC overhead system feeders DPA-27.5-TNF, which is operated on the Trans-Baikal Railway by creating an additional automated system of unified templates necessary for the occurrence of “trainability” elements. The templates will be formed via a separate dedicated channel for transmission, processing and storage of the necessary information, not related to the operation of the terminal, with its subsequent visualization at the workplace of the duty personnel of traction substations, together with information from the “GID” software received via another dedicated wired channel. With the help of such a base of unified preset templates, in the future, it will be possible not only to identify the specific causes of each emergency shutdown but also to reduce their number by dynamically adjusting the existing presets of the standard operation algorithm. 展开更多

Nowadays, people's quality of life has been greatly improved, and the demand for electricity has also been greatly increased. The power industry has brought development opportunities as well as increased development pressure. In order to further meet the needs of people's lives, only by paying attention to the maintenance of the relay protection secondary circuit of the power system can the corresponding power enterprises ensure the stable operation of the power system and create a relatively safe and stable living environment for people. In order to meet these requirements, we must analyze all possible fault types and abnormal conditions in the power system, and analyze the response of relay protection to each type of accident. In addition, the possibility of misoperation of the relay protection device itself should be considered and a backup protection scheme should be provided. Therefore, it is necessary to analyze the causes of some relay protection faults occurring in the actual operation of the power system and put forward the methods to prevent similar faults. 展开更多

The improvement of social and economic level has promoted the effective development of power resources. As an important part of power system, relay protection can realize the timely discovery and treatment of abnormal equipment and faults in power system, thus ensuring the safe and stable operation of power system. But at the same time, the relay protection equipment also has the risk of failure, which threatens the safe and stable operation of the power system. According to the analysis of power accidents in recent years, if the power system fails, it will cause great losses to the social economy. Therefore, considering the causes and types of relay protection faults in power system, effective measures should be formulated to reduce the probability of faults, reduce the losses caused by relay protection faults, and ensure the safety and stability of power system operation. 展开更多
