With the development of technology, the power system of offshore facilities (for short: power system) is increasingly complex, short-circuit current calculation process also becomes more complex. The simple recursive algorithm can not meet the requirements of short-circuit current calculation in complex power system. The paper, basing on the principle of short-circuit current calculation, taking modeling ideas, created an equivalent circuit model of power system for short-circuit current calculation. The equivalent circuit model can be used to simplify the progress of calculation and meet the needs of the power system development.

To improve the efficiency and accuracy of relay setting calculation of power system, this paper proposed and developed a schematized and open-ended software platform in integrative relay setting. Through the advanced development of the Visio software, the graphical input of the target system topology and component parameters are made possible. The platform can automatically generate PSCAD simulation model according to the topology information and device parameters through an interface program to PSCAD, and use this power system simulation software to improve the accuracy of short-circuit current calculation. With the help of the Bookmark mechanism of WORD software, the platform provides a setting template with general protection components, which forms the basis to realize the open-ended platform. The platform also uses the API interface provided by WORD software to automatically generate the final relay protection setting report document according to the results of short-circuit current calculation and the selected protection setting components. This paper gives in detail the overall framework of the proposed platform, as well as the principle and practice of all the above parts. Moreover, the validity and practicality in improving the automation degree of the relay setting of power plant are shown through practical applications.

In allusion to the problems of convention current protection when it was used to collect circuit of wind farm, the relay protection should consider the short-circuit current of wind generators; The principle of adaptive current protection was described, the fault current and attenuation characteristic of asynchronous wind generator was studied, the scheme of adaptive current protection was proposed for wind farm operation. Taking PSCAD/EMTDC as the platform, simulation and record the voltage and current sample-data of different wind farm operation which can guarantee high sensitivity phase selection, the high accuracy wind generators impedance measure method based on FFT filter DC component is presented , and using MATLAB program achieved the scheme of adaptive current protection. Simulation results demonstrate that collect circuit adaptive current protection is adaptive wind farm operation model, and enhance the operation benefit of wind farm.
