In addition, land subsidence of 5 to 10 centimetres per year is taking place. The climate change phenomenon provokes land areas that are lower than sea water level from time to time. This makes the situation with respect to flooding increasingly risky. Semarang Old City （heritage） as part of principal Semarang area is suffering also from regular flooding and pollution that hamper the revitalisation of the old city. These areas used to be productive lands, but flooding make the existing public infrastructure does no longer function, and residential areas have changed into unhealthy slams. To overcome these problems, the Government of Semarang chooses a polder drainage system to address the flooding in Semarang. In the framework of the cooperation between Indonesia and the Netherlands, these activities consist of research and workshops on Urban Heritage. The scope consists basically of five components： experiences with urban drainage and flood protection in Semarang with a focus on Semarang Old City, field visit to relevant places with respect to urban drainage and flood protection of Semarang Old City, lectures on the relevant aspects of urban drainage and flood protection, exercises to get an insight in the processes that can take place under normal and extreme conditions, formulation of a preliminary plan to improve the situation with respect to urban drainage and flood protection of Semarang Old City.

When the power station is put into production, the operation and maintenance work faces great challenges. At present, most of the operation and maintenance of power stations use information technology to collect the operation data of power stations, but the combination of intelligent analysis and on-site operation and maintenance is not high. Operation and maintenance personnel take monitoring and on-site inspection as the main means of operation and maintenance, which makes it difficult to locate equipment faults and lacks effective processing and analysis of massive data of power stations. The operation and maintenance of a power station mainly depends on the level and efficiency of its operation and maintenance personnel, which leads to low operation and maintenance efficiency. Aiming at the current situation of operation and maintenance, this paper puts forward the research of designing intelligent operation and maintenance system for photovoltaic power generation. MySQL database is used to store SCADA data of inverter, and the massive data are preliminarily screened, and then the screened data are further intelligently analyzed through cloud platform. The historical data, real-time data, on-site inspection data and on-site inspection of the inverter side are comprehensively analyzed and judged. Excavate the potential safety hazards, weak links of safety production and the main factors affecting the electricity quantity in the production and operation of photovoltaic power plants.展开更多
