The Whole Process Of Technical Management Over The Synchronzer In Inner Mongolia 500kV Substation

SGC company (southeast shanxi - nanyang - jingmen) 1000kV uhv demonstrationengineering commissioning, Inner Mongolia "three horizontal grids also provids 500kV fourlengthwise" preliminary already built. High voltage, distribution parameters, big power gridmanagement operation to the safe and reliable operation of the power grid has broughtserious challenges, power grid has expanded rapidly, running condition is complicated, safetyresponsibility getting worse is the current electric power industry facing the basic situation ofproduction safety.The current with Inner Mongolia electric energy base, "wind of the construction of thethree gorges" power fast development, the wind power, hydropower and (self-provided)power plant of access in nets unit equipment 500kV substation, Inner Mongolia 500kV gridnetwork structure is more and more complicated, to operate 500kV substation in existenceand power plant, isolated when not running the same power tied the possible. At the sametime, in order to ensure power grid failure occurred in solution columns can be resumed assoon as possible recover the capacity, secure and stable operation of the grid, minimize theisolated net running 500kV substation, and therefore the same system management put on theagenda.Tied to the same power system requires a high degree of operation, if improperoperation or incorrect operation, will produce a great impact, light is cause the system currentvoltage fluctuations, heavy then cause the system oscillation, damaged electric equipmentand endanger the safe and stable operation of power system. The correct reasonableinvestment period generator, transformer substation, can quickly turn generator system(independent system) merges into system, rapid return to normal power supply, avoid thesame power system the justaposition of happen, ensure the safe and stable operation of thepower system.This paper briefly introduces the same generator, transformer substation, according toprinciple of power system juxtaposed with the same requirements of substation of InnerMongolia, same 500kV substation study, analysis, system proposed whole same technicalmanagement system. From the same 500kV substation management system for substation weak, to the same measurement device function the same secondary circuit and measurementdevice is the realization of the function of the same function (same the retreating, embossed,field calibration, setting value setting) for the actual research, analysis and census, especiallyin accordance with the power network operation mode and the generator, transformersubstation each interval operation analysis, determined the same way the same point andsubstation, demonstrates the same period of Inner Mongolia 500kV substation systemfunction, regulate the necessity and feasibility of the system management, puts forward thesame 500kV a suitable period of substation field management system of feasible scheme,formed in guiding the actual work the same 500kV technical management standardizationand research system and completed the whole period of Inner Mongolia 500kV substationtechnology management system for substation, same 500kV systematic study provide thesolid technical foundation.In addition, this paper also introduces the wide application of power can automaticallyidentify with frequency grid and same difference frequency combined lines, and alsointroduces the device of substation integrated automation of the same measurement deviceand the function of the same generator, transformer substation system was prospected.
