The present invention provides a three-level protection setting calculation method for distribution network based on Simulink simulation. By establishing a distribution network "outlet + branch + boundary" three-level relay protection coordination model, the principle of each level switch setting calculation is clarified. Use the Matlab callback function to let the user input the switch parameters, and realize the calculation of the called value, create a simulation model to generate the topology diagram of the distribution network, and judge the coordination between the protection setting of the switch and the protection setting of the upper and lower switches and the occurrence of faults When the switch protection action, choose to return to modify the switch setting calculation principle or generate the corresponding calculation draft and value list to send to the maintenance work area. The invention gets rid of manual calculation, avoids the reduction of efficiency and accuracy, facilitates technical personnel to check the correctness of calculation, and is beneficial to subsequent analysis and data storage.

The invention relates to a light hydrocarbon density instrument, which comprises a tester for accommodating liquid to be measured and an electronic balance with a peeling function, wherein the tester comprises an end cover, a liquid inlet bucket and a transparent burette tightly connected between the end cover and the liquid inlet bucket; a liquid outlet air exhaust port communicated with the top of the transparent burette and a liquid outlet valve for controlling the liquid outlet air exhaust port to be opened or closed are arranged at the upper end of the end cover; a liquid inlet and a liquid inlet valve which is used for controlling the liquid inlet to be opened or closed are arranged at the bottom or the side edge of the liquid inlet bucket; a plurality of uniformly distributed screws are arranged between the end cover and the liquid inlet bucket, so that the end cover and the liquid inlet bucket are fixed by the screws; sealing rubber rings for preventing liquid from leaking are arranged in the top and the bottom of the liquid inlet bucket; a scale for indicating the volume of the liquid of 1,000 ml is formed on the transparent burette; and the liquid inlet bucket has a hollow structure, and is communicated with the bottom of the transparent burette. The invention also provides a method for measuring the density of the liquid by using the light hydrocarbon density instrument. The light hydrocarbon density instrument is convenient to use, low in cost and convenient to popularize.
