In this paper, we propose a verification method for risk management system of the electric power grid (RMS-EPG) using satellite communication network. The RMS-EPG with satellite communication network should be verified with various contingencies for its design and maintenance. For the verification of RMS-PG, the proposed system composed of the satellite communication simulator and the Power flow emulator. Proposed simulator of satellite communication can evaluate not only the delay of communication with satellite but also the robustness of satellite communication according to the change of weather using simulation model for ITU-R 839. And the proposed emulator of Phase Measurement Unit for Satellite communication (sPMU) can realize its function that calculates the voltage stability by hardware implementation using FPGA. Using the proposed verification system, we verified its function of RMS-EPG for the power grid of Jeju Island in Korea

There are several types of communication method which is used for the supply of electric power stably. But the communication methods used in KEPCO have weak points in the viewpoint of economy. technology and management. The Satellite communication systems have competitive power in price and technology for national wide utility owing to its wide area coverage and stability. This paper presents various adapted examples of the Power industry using he satellite communication systems.

산업발달로 인한 전력산업 구조변화와 해마다 증가하는 전력소비는 전력계통의 복잡성을 증가시켜 전력품질의 신뢰성과 안정도 확보룰 위한 계통데이터의 실시간 수집 및 감시/제어의 중요성을 부각시키고 있다. 또한 최근 몇 년간 선진국에서 발생하는 대정전사고는 전체 계통의 유기적인 흐름과 변화를 감시할 수 있는 시스템의 필요성을 인식시켰으며, 이를 위해서 선진국에서는 광역계통감시시스템 (WAMS)의 개발에 집중을 하고 있는 실정이다. 본 논문에서는 한전전력연구원에서 연구중인 광역계통감시시스템과 전력계통에서 시각동기 데이터를 취득하는 sPMU의 구조와 전력계통에 최초로 적용한 위성시스템에 대하여 기술한다.
