Converter control model plays an essential function for HVDC system dynamic simulation in real time simulator (RTDS). RTDS can provide approach for detailed studies of options and predictions of the system performance. This paper first presents the basic principle of the power control, firing control and transformer tap control. Then the paper presents our modeling effort for these control models. The configuration of control models includes major sections of practical controls. The paper also makes final verification test of these sections with a typical power system model. The validity of proposal methods and designed simulation model is verified by tests and computed results. The built HVDC control model is competent for the RTDS simulation.

The paper introduces the theory of maximal wind energy tracking based on wind turbine aerodynamic theory, based on which methods to realize are provided and control subsystem is build on RTDS. Simulating results on RTDS, of whole DFIG wind generating system, showed the method is feasible and the control subsystem is correct and effective.

In view of the current network structure of the Smart Substations in China, the industrial Ethernet is analyzed with respect to the presence of long latency that may be found in the communication of Smart Substation, the configuration complexity that is not conducive to repair and the maintenance involving relatively high economic costs. A connection-oriented switching network technology is then proposed on similar issues, with a leaky bucket model being built up based on the substation information flow. Subsequently, the service classification and priority scheduling mechanism are placed to introduce the network calculus to calculate the delay bound of each of information flows. Conclusively, based on the IEC62439, a network communication method for Smart substation is established to solve the problems with the Industrial Ethernet application in smart substation.

This paper deals with the study of smart substation system level test. The test include three parts:network performance test,electronic transformer test and conformance testing.Network performance test involves the process layer network and station level networks test, transmission delay and frame loss rate of switch is tested.Electronic transformer test contains accuracy test, absolute delay test and polarity test. Conformance test is a test for model based on IEC 61850,test flow is studied.
