“…to improve practical working ability, through both simulation systems [1][2][3][4][5][6] and training substations [7,8]. Besides, substation auxiliary decision-making systems [9,10] are developed to assist in diagnosing the operating status of equipment. However, real-time work assistance tools that can directly instruct substation work processes step by step are still in absence.…”

Work assistance is one of the important means to improve work efficiency. This paper focuses on substation work and proposes a real-time work assistance method based on petri net model. The work assistance includes two aspects, termed as, workflow guidance and operation prompt. Particularly, the workflow constructed by the petri net includes sequence, inhibition, concurrency and conflict structures to declare the correlations between work steps. Further, different forms of operation prompts at each step are designed, considering real-time responses of workers including skip, replay, pause and restart. The effectiveness of the method is well validated by an application of the work assistance on measuring the grounding current of transformer core and clamp. It is demonstrated that the unified assistance method built by the petri net successfully instructs standardized working process, helps avoid potential risks, and provides flexible operation prompts in real time.

The introduction of intelligent substation process layer network has caused great changes in the data source and transmission method of relay protection, and its action performance and reliability are increasingly dependent on the communication network. The data flow of the relay protection in the intelligent substation and the communication mechanism of each message are analysed. Based on the IEC61850 standard, the process layer network and the relay protection IED device are modelled on the OPNET simulation software to realize the MU of the relay protection in the intelligent substation the whole process simulation of data collection, SV message, GOOSE message, protection algorithm and protection export. Combined with the example of current protection, the principle and realization mechanism of modelling and simulation are explained, and its feasibility and effectiveness are verified, which provides a new effective research tool for the quantitative analysis of relay protection in smart substations.
