Research On MCR Based-SVC Of Tangshan Daodi 110kV Transformer Substation

With the quick development of national economy, More and more with non-symmetrical, non-linear characteristics and impact of civil and industrial electrical equipment connected to the power grid. The resulting low power factor, voltage fluctuations, voltage phase unbalance, harmonic pollution, and many other power quality pollution. Electric power system on the quality of the goal is to network security, quality, economic performance Therefore, the power system's control of reactive power and voltage requirements of more and more attention. Electric power system on the quality of the goal is to network security, quality, economic performance, therefore, the power system's control of reactive power and voltage requirements of more and more attention.Adapt to the development of Tangsan Power Grid and electric power market construction, Needing to be a kind of is more ideal of compensate a technique without the achievement to carry out these requests.Static Var Compensator SVC (Staticvar Compensator) is the most widely used, but also solve the high cost of a power quality device New magnetron reactor is a DC current by changing the excitation to alter the magnetic core saturation of the device, the work can be used to control small DC power coil core of the saturation level, so as to control the inductance value And reactance into the current size of the grid to achieve a smooth adjustment of the purpose of reactive power grid in recent years, MCR its excellent overall performance in the static reactive power compensation devices have been widely used.In this paper, MCR + FC-type SVC as the main object of study, describes the MCR + FC-type SVC application technology, and according to the Tangshan Daodi the actual needs of 110kV substation load carried by the technology implementation of the project design, equipment installation put into operation, in the community , Economy, technology has made good results.
