A comprehensive test platform for smart substation

Abstract

The invention provides an intelligent transformer station comprehensive test platform. An intelligent transformer station comprises a process layer or station layer network, a process layer device, a bay level device and a station level device. The comprehensive test platform comprises a main control board, a synchronizing signal power bus and two interface boards. One sides of the main control board and the interface boards are provided clock synchronization and power supply interfaces and optical fiber interfaces. Two ends of the synchronizing signal power bus are connected with the clock synchronization and power supply interface of the main control board and the clock synchronization and power supply interfaces of the interface boards. The optical fiber interfaces of the main control board are connected with the optical fiber interfaces of the interface boards. The platform adopts the electromagnetic transient simulation mode to provide the detected intelligent transformer station with the simulated real power grid operating environment. By setting up various complex faults, it is possible to detect the correctness of the single device, the single interval and mutual cooperation among all the devices in the intelligent transformer station, and solve the problem that the closed loop test cannot be carried out onsite and the device interoperability cannot be verified at the same time.

Description

technical field [0001] The invention relates to a substation detection device, in particular to an intelligent substation comprehensive detection platform. Background technique [0002] The accuracy of smart substation information not only directly affects the realization of substation intelligence, but also affects the operation status of smart substations. Therefore, how to ensure timely, accurate and complete acquisition of sufficient substation operation information, and quickly and accurately analyze these information Processing, grasping and predicting the operating status of the smart substation in real time, giving early warning to various abnormal situations, taking timely measures to prevent the occurrence of faults, and continuously evaluating it according to the actual operating status of the substation, so as to effectively ensure the construction of the smart substation project and operation and maintenance are very important. [0003] Although the new generat...

Problems solved by technology

[0003] Although the new generation of smart substations has begun to be promoted on a large scale, the debugging technology and means based on the relay protection tester are very limited, and its functions are relatively monotonous, which can no longer meet the needs of the new generation of smart substation debugging; in addition, the steady state data and dynamic data of the substation The acquisition systems are independent of each other, the time scale is not uniform, and the data cannot be shared, which is not conducive to advanced applications such as accident analysis and dispatching systems for state estimation
