The invention discloses a small, micro-power and low-price portrait analysis system for a power supply enterprise, and the system comprises a risk related information extraction module which is used for extracting risk related information which is stored in a database, and the risk related information comprises a risk factor and an x value corresponding to the risk influence factor; the risk influence factor extraction module is used for calculating an influence coefficient and a risk index of a risk related information risk influence factor by adopting a linear regression model; a portrait display module, wherein the portrait comprises word cloud picture distribution of a central area and basic information on the periphery of the word cloud picture; wherein the words in the word cloud picture are risk influence factors, the sizes of the words are related to the risk influence factor coefficient, and the larger the coefficient absolute value is, the larger the incorruption risk influence is, and the larger the word display area is. The system achieves the timely monitoring and display of the incorruption risk.
