碩士 === 國立政治大學 === 經營管理碩士學程 === 90 === The salt contamination caused a series of problems on the control systems of the 3rd nuclear power plant in the 318 3A Accident. In a more general case, the salt contamination would result in the instability of power system and might cause the power system to shut down. Although salt contamination problem prevails in Taiwan due to geographic condition, statistical data and relevant research salt contamination severity does not exist. This research will systematically analyze the impact of salt contamination and then suggest corresponding solutions. This study focus on the salt contamination on the transmission and distribution system rather than the power generating system, since the utility distribution can utilize the back up system when overloaded. To provide concrete descriptions and solutions for salt contamination problem, we choose the distribution system of Yun-Lin district office as our case study subject. We first collect the practical operation and experience of other utility companies (e.g. Formosa, Japan utility company, and Korea utility company) as our general references. To seek for practical suggestions of the problem, we then interview with field experts. We find that the distribution systems along the sea shore incur serious salt contamination problem and Yun-Lin County is the most serious area in which much manpower and money have been invested in related maintenance. The internal rule of Taipower Company （TPC） however prescribe the general cleaning frequency and method only. Such common rule is not suitable for every kind of environments. The accident rate caused by the salt contamination hence is quite high. On the other hand, the Mai-Liew power plant and other utility companies in Japan and Korea use the anti-contamination equipments and tools as well as standardizing monitoring mechanism to deal with the salt contamination problem. They regularly measure the “Equivalent Salt Deposit Density” values to monitor the severity of salt contamination. The periodical data is then analyzed for necessary prompt actions. The 318 3A Accident of the 3rd nuclear power plant had evoked the attention of the society. All parties recognize the fact that the instability of utility system could result in serious accident. The society demands the good power supply quality that is stable and adequate. TPC should adopt the loss and prevention management by using high tech products and other risk controlling method to avoid the occurrence of similar accidents of the 3rd nuclear event in the future.
