Electric Power Automation Control System Based on SCADA Protocols Shihai Tan

Abstract The operation of the power failure can be catastrophic national security and economy. Due to complex, the dispersed of assets of dependent relationship among computer, communication, and power systems, to meet the safety requirements and quality requirements of the operation is a challenging problem. In recent years, the cyber security standards jointly sponsored cyber security utility, in compliance with the control system-CIP 1200. Common to this standard, identification of the existing security hole, a few cyber-that will offer an control system, and introduces several measures (for example, best practice). This paper summarizes cyber security problems control and automation systems, power control structures, and the possible existence of vulnerability assessment system. Keywords Electric power automation control

17.1 Introduction Electric power system is connected through a highly automated network. Some communication networks interconnected to power grid for the purpose of sensor, monitoring, and control. The computer and communications equipment is widely installed in power plants, transformer substation, energy control center, the headquarters of the company, regional operating office, and big load sites. These devices and systems become more network and complex [1].

Computer, communication, electric power infrastructure are dependent on the grid. Measurement and control signal is obtained using SCADA energy management system (EMS) power system for a wide range of system function, including real-time control power grid. Failure of an important communication channel operation environment, can lead to control or operate important facilities, which can lead to possible power outages. Communication network congestion could delay the transfer of power system data and control signals, and, in some cases may be critical [2]. Another hacking scene is a breakthrough of the substation and other change settings protection relay, which may lead to bad switch action. At present, the system may not have strong measures to network attack, thus the existence of the loopholes. Therefore, there is a growing demand cyber security to solve these problems, in an overall and systematic way. It has the advanced SCADA agreement from point-to-point links update the agreement and communication method [3]. The new method allows a higher level of redundancy and the spread of speed. The important question is, the practice is a mixture of the original 1970s and today’s standards of practice. The reason for this may be expected of SCADA equipment. Life of the operation equipment is from 15 to
