Research and Application of Collaborative Testing Technology for Safety and Stability Control System Based on Distributed Simulation

摘要

In order to solve the instability problems of voltage, power angle and frequency in Xinjiang power grid, Xinjiang power grid is equipped with a large number of security and stability control systems to ensure the stable operation of the power grid. However, the existing stability control system test can not realize the comprehensive test of field operation equipment. In order to solve the above problems, this paper proposes to use the existing power dispatching data network and 2M communication channel between stations to establish a distributed collaborative test platform for stability control system. The platform is based on the distributed ADPSS (all digital real-time simulation) technology and power communication network, it designs re-mote interface device and field test device. And the platform studies the information transmission mechanism between the distributed ADPSS simulation platform and the field test device, as well as the synchronous test technology between the field test device and other technologies. So as to realize the remote, on-line and closed-loop comprehensive test of the security and stability control system. The platform can effectively improve the standardization of stability control system inspection and joint commissioning, reduce the manpower and material resources involved in joint commissioning and maintenance of cross regional system, and greatly improve the safety and reliability of the stability control system.
