Abstract

A communication method between the power plant and the power grid in the power system machine network coordination simulation model: the S1 power plant power system simulator outputs the mechanical power P of the steam turbine M It is sent to the real-time digital simulator RTDS of the power grid through the communication interface; the real-time digital simulator RTDS of the S2 power grid calculates the rotor speed ω of the generator and the output electric power P of the generator. E And generator end power U; S3 power grid real-time digital simulator RTDS sends the result of step S2 to the power plant power system simulator through the communication interface. The invention can realize the machine-network co-simulation of the power system of the thermal power plant and the power grid system, so as to establish a machine-network coordination laboratory platform, study the characteristics of the power plant and the power grid, analyze the power plant control equipment such as the governor and the excitation regulator, relay Interaction between electrical control devices such as electrical protection.

Description

technical field [0001] The invention relates to a communication method between simulation models, in particular to a communication method between a power plant and a power grid in a power system machine-network coordination simulation model. Specifically, it is the method of data interaction between the power plant power system simulator and the power grid real-time digital simulator RTDS. Background technique [0002] In the development process of power system, power system simulation has been playing an extremely important role. Simulation can be used to study the feasibility of future power system projects and predict the future performance and possible bottlenecks of the system. Simulation can also effectively analyze the fault conditions that actually occur in the power grid, and formulate correct protection and limiting measures. Using simulation can also optimize the power grid, effectively improving the economy and reliability of system operation. [0003] Power s...
