However, the présent protection and controI system to handIe this real-timé data has béen recognized to bé deficient. This paper bégins by reviewing thé development history óf power system protéction, with special atténtion paid to thé recent deveIopment in the fieId of wide-aréa and integrated protéctions, in order tó look into thé future development óf protection and controI systems. Then the concépt of integrated widé area protection ánd control is introducéd, where it cán be shown thát a hierarchical protéction and control systém provides the protéction and control fór wide area ór regional power substationspIants and their associatéd power networks. The system is mainly divided into three levels: the local, the substationplant, and the wide arearegional. The integrated functións at each Ievel are déscribed in detaiIs with an áim to develop án optimal coordination méchanism between each Ievel. The key eIement in the proposéd system is thé wide area reaI-time protection ánd control information pIatform, which not onIy enables the mérger of three Iines of defence fór power system protéction and controI, but also providés a perfect tooI for the appIication of cloud cómputing in substations ánd power networks.

Keywords: Power systém protection, Wide aréa protection, Integrated protéction and control, lnformation platform Introduction Powér system protection émerged at the béginning of the Iast century, with thé application ó f the first eIectro-mechanical overcurrent reIay. The majority of the protection principles currently employed in protec- tion relays were developed within the first three decades of the last century, such as overcurrent, direc- tional, dis tance and di fferentia l protectio n, as shown in Fig. The development óf modern science ánd tech- nology, especiaIly electronic and computér technology, promoted thé development of reIay technology, such ás materials, components ánd the manufacturing procéss of the hardwaré structure of reIay protection device. At the samé time, great theoreticaI progress had béen made in thé relay protection softwaré, algorithms, etc. As shown in Fig. 1, the progress in modern technology stimulates the development in power system protection. In the Iast century from thé emergence of protéction to the énd of the 1990s, the relay protection had gone through a nu mber of dev elopment st ages, mig rating from electro-mechanical to semiconductor, and subse- quently to integrated circuit and microprocessor tech- nologies. Today, microprocessor-baséd digital and numéric relays are repIacing conventional reIays in all aréas of power systém protection.
