2.ĭistribution substation: to decimate the power level for the distribution level consumers, a distribution transformer is used. These transformers are inserted in the grid system to improve the power efficiency of the system by reducing the transmission line losses.
Transmission substation: for connecting two or more than two transmission lines, via grid breakers. Transformers at substations, can be classified in different (possibly disjoint) groups, with respect to their voltage levels (power levels), function in a power grid, insulation class, or construction, etc. Substation is an important element of power transmission system that has transformers (and other power system components). For the AccessPoints connected only to the GOOSE network in the process level, devices in SCD files should define Inputs in LN0 of LD to receive the GOOSE input from the GOOSE network and define GOOSE datasets and GOOSE control blocks to send GOOSE signals. The device should support multiple independent GOOSE networks by supporting multiple AccessPoints in the ICD file. The IntAddr in Extref describing the address of inner input signals should be filled with DO signal name starting with GGIO, that is, “LD/LN.DO.DA.” (6) Each GOOSE connection line contains the input virtual terminal inside the device and output virtual terminal outside the device. In the SCD file, the Inputs part in logic node LLN0 of each device defines the input GOOSE connection of this device. The GOOSE input signals are grouped with different GGIO numbers. Due to the DO and dU description in the GGIO, the meaning of this signal is described to guide the linkage of GOOSE.
DO signals are defined in GGIO logic nodes starting with prefix “GOIN.” DO signals are corresponding to external GOOSE input signals. Input GOOSE signals of devices use the concept of virtual terminals. The GOOSE output signals should be configured in the GOOSE dataset of the device ICD file (except for the GOOSE signal of interlocking). The output dataset of GOOSE should support DA.
The fundamental requirements for GOOSE configuration are as follows: (1)Ĭommunication address parameters are configured by the system configuration tool, and the device will apply the GOOSE according to configuration. In configuration files, GOOSE configuration is divided into GOOSE sending and receiving configuration.
