Abstract

The intelligent measure-control system between intelligent electronic device and communication device of 10KV distribution substation comprises: an information treatment unit with a CPU electric connected to a inner memory, an external memory, a CPLD, a quartz-oscillator, and a Watchdog as well as other said units; a first and second communication unit, a measure-control unit, a system maintenance unit, and opposite control software. Wherein, preparing circuits of said information unit, two communication units and maintenance unit on one primary circuit board while the measure-control unit on expander board connected with primary board by flat cable. This invention connects to existed IED to realize collection for measure-control information and remote send to control center for remote control operation.

Description

technical field [0001] The invention relates to a 10KV distribution station, in particular to an intelligent measurement and control system for monitoring a small 10KV distribution station. Background technique [0002] With the rapid development of my country's national economy, the demand for power supply is increasing, and the peak load is increasing. In recent years, in order to alleviate the contradiction of power supply shortage, the power supply department has invested heavily in the construction of the power grid, which has become larger and more complex; on the other hand, by optimizing the management of the existing power grid, the utilization of power supply equipment rate and improve power supply capacity. [0003] As the terminal network connecting users in the power grid, the distribution network is more than ten times larger than the main power grid. Therefore, mastering the real-time monitoring information of the distribution network can greatly improve the...
