The invention relates to a power system analysis-oriented software distributed development method. The method comprises the steps of establishing a server and a client with communication functions; performing distributed development of a software algorithm, and calling basic data and a universal algorithm of the server through the client by a development team to perform development and research of corresponding algorithms; and performing achievement gathering of software, and seamlessly linking algorithm achievements of the development team with the software server, thereby realizing distributed development of the software. According to the technical scheme provided by the method, the problem in sharing of the basic data and a basic algorithm in the software establishment process is solved, high cost of integrated development is avoided, the development speed is increased, the seamless fusion of the algorithm development achievements and the software is realized, and the software achievements have portability and reusability.
