As the revolutionary change in electric power industry begins with the latest communication infrastructure, it is on the verge of a revolutionary transformation to develop a smart grid to meet the requirements of our digital society. Wide Area Power System is made up of plentiful automated transmission and distribution systems with strong communication infrastructure, all operating in a coordinated, proficient and reliable mode. This paper is fretful with the wide area power system load protection scheme and ensuing design requirement that enhances stability as well as control. It discusses the architecture that upgrades the existing scheme by controlling all the control signals traffic between generating units, server, connected loads, and protection devices using WIMAX. The main theme of the paper is on the use of information technology to obtain more flexibility and smartness in the Wide Area Power System Load Protection by designing the Communication channel using WIMAX. Faults detected in Local area networks and Information regarding the faults of Local Areas is communicated to Load Area Manager (LAM) which takes required control action to handle it. Finally the paper shows islanding operation through WAM for the areas that becomes intensive faulty. Results have been verified in MATLAB/ SIMULIMK.

“…Probably, the most well-addressed distributed control case is to apply synchronized phasors to damp the inter-area oscillations [32]. Alternatively, there are also proposals for centralized control applications based on phasor information, i.e., fast load-shedding for voltage control [33].…”

This position paper presents initial research and investigation on a unified framework combining two independent systems, the legacy SCADA system and the synchronized phasor data system, that share the same measurement sources, i.e., current and voltage transducers and the same communication medium. In this framework, conventional SCADA system coupled with substation automation system are modeled together with synchronized phasor systems. The contribution of this paper also includes a state-ofthe-art survey of topics related to the proposed architectures. Furthermore, an overview of the data flows between substation and control centers including both SCADA and phasor measurements are presented. Taking into consideration the growing interest in communication and automation standardization this paper also addresses the communication between the substations coupled with relevant standards and technology.

“…Wide area protection is based on a wide area measurement system (WAMS) that implements a regional protection and control system [2][3][4][5][6][7]. This was developed from special integrity protection systems (SIPS) [8] and broadened the role of traditional relay protection from a point to a surface, so that the high standards of dependability and security inherent in modern protection systems can be maintained [9]. Wide area protection responds to various system disturbances through the analysis of wide area information and the evaluation of the system states.…”

Facing the growth of energy demand and the worldwide interests in renewable energy sources, smart grid has been proposed in order to accommodate the needs of power grid development. In China, digital substations have been widely applied. Moreover, as the worldwide interest and development in smart grid have increased significantly, the digital information availability and communication capability of modern substation have been improved. Different with traditional substation protection configuration based on local information, Integrated Protection (IP) is used to denote the integration of several protective devices for multiple power equipment within the substation into one protective relay, obtaining all the real time information of the substation by communication network. The analysis of sharing information and cooperation among different protection functions helps to realize more reliable and sensitive fault detection. This paper describes several different integrated protection schemes and their respective advantages and disadvantages. The principles and functions applied in integrated protection systems are addressed to provide an overview of the current state of the technology. A new coordinated protection system based on inter-substation information is proposed and simulation study is discussed to verify the improved reliability and sensitivity.
