RESEARCH AND APPLICATION OF GPSR662-102 DEVICE

ABSTRACT

With the continuous development of China's economy and increasing demand for electricity, the safe and efficient operation of electric power is very important, and the requirements for power equipment are more intelligent. The development of electric power has entered a new development period, and the integrated automation technology in the power system is widely used, especially the construction and operation of substation and transmission and distribution line automation. Substations with unattended technical conditions are being popularized in various provinces and cities.

With the wide application of microcomputer protection, as the key equipment of protection device, the protection of microcomputer based measurement and control device has been widely used, and it has the function of network. It can be well combined with the integrated automation system of the substation. This paper selects the knowledge of related specialized courses such as relay protection, microcomputer protection, substation automation and two circuits. Through the analysis of 1 sets of complete set of measurement and control cabinet drawings and the drawings of the matching circuit breaker, knife gate and relay protection cabinet, the application ability of the two part of the work of the students is strengthened. According to the construction drawing of the two circuits of 110kV line protection is designed according to the actual equipment, and the students have certain specific engineering application ability to the substation integrated automation system, especially the two circuit part.

The biggest feature of the two connection is that the action of its equipment and components is strictly in accordance with the order of design. It has very strong logic. This design introduces the functions of circuit breakers, design principles and external connections, the configuration of the two system equipment and the functions and Realization of each circuit. According to the two circuit designs of ABB145 circuit breaker, CS600 type knife gate electric mechanism, CS100 type ground knife manual mechanism, GXH163A line relay protection cabinet and GPSR662-102 type measurement and control cabinet, the AC voltage, and the comprehensive training of the research and design of the actual problems is carried out.

1.1 研究背景与意义

随着我国经济的不断增长和社会的不断进步,电力作为重要的动力来源,其安全稳定运行和技术的不断进步,为经济社会提供了重要的支撑,创造了巨大的经济效益。继电保护是电力系统安全经济高效运行的重要子系统,在电力系统发生故障时,起到保护电网安全作用。

继电保护装置被称为电力系统的无声警卫,在电网发生故障时可以在很短时间内进行故障切除动作,其他时候保持不动作状态。但是继电保护装置自身错在某些缺陷的时候,没有被察觉会造成保护装置误动和拒动,从而继电保护失灵,造成更大的故障。微机保护的应用使得保护装置具有自我监测和自我监视的功能,从而避免出现因保护装置自身的问题造成电网故障。
